Yes, sure. That'll print a tenth of the value of $x. The '.fmt("%s")'
is a no-op in this case.

Not entirely a no-op. Thus
$perl6
> my $x=:a<5>; say $x.map({.value/10}).fmt("the value is %s%%")
the value is 0.5%
But we have lost the .key part of the pair

Null PMC access in get_string()
Still, even if we could do something like (which we cant with rakudo,
not sure if this is possible in perl6 in principle)
say $pair.map({.key => .value*100/$count}).fmt("Candidate %s has %s
percent of vote");
would it be more elegant than
printf("Candidate %s has %s percent of
vote\n",$pair.key,$pair.value*100/$count);
I dont think so.
A Logo design for Rakudo Perl 6
Hello everyone, A few weeks ago, probably more than I want to admit (but here! See! My Notes! I've been up to something!), there was one of those, "OMG! Perl is going to DIE!" threads, somewhere and the, "Well, do something about it" call came out, and I sort of replied, "well, alright" and gave my open ended hand to some design work. Moritz was one of the first to guide it to the idea of making a logo for Rakudo Perl 6 - as there's nothing yet (really) available. I thought that would be a neat project and scratch some of my person itches. A slight background on me: I'm that guy: http://xkcd.com/519/ (Although, there should be two more columns for, "Skateboarding" and, "Rock Climbing" in there). I really started working with Perl during a internship in college which started me in a full time job doin' the stuff, which got me to where I am today: just working for myself. In all of that, I also managed to get through Art School (guess what paid for *that*!). A lot of my work deals with language and text, writing and communication. Some of my work bordered on generative work, but most of it stayed on the canvas, as I wanted to go to school to learn to paint. Anyways, I've always wanted to help out on larger-than-myself Perl projects, but, although I think my perl-fu is, well, alright - it's not wizard-like. But! I think an interesting niche that I could fill is as someone who, "gets" Perl and it's wonderful and varied culture and also, "gets" visual communication and all that. I am a firm believer that a healthy community is one full of diversity and successful projects come not out of one genius, but of many just normal people, and that's me: just a normal person. Here's some notes I've collected about what people have said Rakudo Perl 6 is, which is a good baseline on what a logo should try to reflect and communicate: Rakudo Perl is: Perl 6 on Parrot Rakudo as a *implementation* of a *specification* Rakuda-do (Japanese): Way of the Camel Rakudo (Japanese):Paradise Camels, Paradise/Oasis, etc. It's good visuals and it's easy to digest. Camels are mean and smelly close up, but we don't have to get all that close - it's good to remember they're also extremely useful and in some places, absolutely critical to ways of life. It also doesn't stray far from the original Perl 5 image of Camels and Pyramids and all that jazz. The Japanese lean on all this seems important too, perhaps to get a little more mindshare from the folks that find Ruby interesting and attractive (more on that in just a little bit) One of the main fears with this name, "Rakudo Perl 6" - at least when it first came out, is that describing Rakudo Perl as, "An implementation (one of possibly, many) of the Perl 6 Specification, built on top of the Parrot Virtual Machine", will leave people going, "Huh?!" I think this is a good reason as anything, to think of getting a visual representation of this, somewhat complicated idea out ASAP. It's interesting that Japanese Word(s) were chosen as the new name - it's grown on me - I like it. Japanese Art and Poetry has the idea of the, "haiga" and the, "gō" - which is sort of like a pen-name, but it changes if there's a change in the style of the artist during their career. You could think of, "Rakudo" as a new, "haiga" for Perl - at least the concept makes things clear to me: we've changed course, but it's still the same hand. I was also, incidentally, doing some research on the origins of the Latin alphabet - I'm very curious about languages in general - mostly how they're abused in media and popular culture, but also in learning new ones - I took a brief stint solo in France armed with a 5 week Free University course in French to see how well I could get along. Eye-opening. I happened upon the book, "Mysteries of the Alphabet" (Narc-Alain Ouknin - originally written *in* French) in the shelves of someone I was hanging out with. It's main thesis, really is the Latin/Greek alphabet started with something they term the, "Proto-Sinaitic" alphabet, which was created around the time the lost tribe of Israel was figuring itself out. Moses and all. One of the, well, the third letter in their alphabet is, "gimmel", which comes from the word gamel, which, if you didn't guess already means, "Camel"! It looks either like the neck of a camel - or, perhaps it's hump. If you think of, "gimmel" as our, "C" you can sort of still see a hump of a camel, if you just turn the, "C" 90 degrees, clockwise. Early written languages like Proto-Sinaitic are sort of the beginning where pictograms that stood for what things looked like, where changed into a way of writing about an idea - a lot of these early letters still hold a lot of the original meanings. Hebrew, for instance still does and each character is rich in back history. I like the Prot

First, I totally agree that Rakudo Perl needs a logo, and the sooner we can get one to start using on our website (which we're now creating) and other materials, the better. So, your thoughts and ideas are quite welcome. Beyond that, I think your message has neatly captured many of the facets of what we're working with (and yes, there are a lot of facets). The message reminds me of some of Larry's "State of the Onion" addresses -- looking at many sides of the Perl (in this case Rakudo Perl 6) world. So, my primary comment is that I find myself very much in agreement with your proposal, and a strong hope that you'll continue on in this direction. I agree with the idea of the style guide and some simple elements that people can combine together in very expressive and beautiful ways. Indeed, it sounds very much like you're proposing an ideographic system for Rakudo Perl, where can combine graphic symbols for ideas together. That feels very Perlish and Rakudoish to me -- I like it. So, I'd say "press on" and let us see what you come up with. :-) Some other minor reflections on your post: > One of the main fears with this name, "Rakudo Perl 6" - at least when it > first came out, is that describing Rakudo Perl as, "An implementation > (one of possibly, many) of the Perl 6 Specification, built on top of the > Parrot Virtual Machine", will leave people going, > > "Huh?!" > > I think this is a good reason as anything, to think of getting a visual > representation of this, somewhat complicated idea out ASAP. I agree fully about the need for a visual representation; as far as the name goes I'm hoping that people will think of "Rakudo Perl" in a manner to the way that we currently think of "Strawberry Perl" or "Vanilla Perl". > Taking a step back from this soup of ideas and thinking of a logo > itself, it seems that it would help to produce something that's made of > somewhat interlocking and inter-related pieces: Perl on Parrot has two > separate pieces that come together and complete an idea.

I can't really speak for what Parrot will want or need, as they already have a (very nice) logo. But having a symbol to represent Parrot in the system you propose would likely be very workable. > What I really *really* need now is some feedback for any and all of the > above research and braindump. My feedback is essentially "Sounds fantastic!" and I'm eager to see where it leads. If I can be of further help, please ask! Pm

Huh?! ;) AFAIK. Strawberry Perl is a binary distribution of perl5 for windows. I thought "Rakudo Perl 6" was ( equivalent to "perl5" in the sentence above ) either "going to become perl6" or "already perl6". Is that the case, or is there not going to be a(n official) "perl6" or are there going to be many "perl6"s ? Yes, I know there is pugs but I thought that was a prototype. -- --gh

Perl 6 is anything that passes the official test suite. This test suite was initially developed under the Pugs project because that project is the furthest along in exploring the high-level semantics of Perl 6. (Other projects are better at other things, such as speed or interoperability.) However, the Pugs project views the test suite as community property, and is working towards platform neutrality, so that Perl 6 is defined primarily by its desired semantics, not by accidents of history. ~jerry
Re: A Logo design for Rakudo Perl 6
Perl 6 is a language specification, tied to a test suite. It will have as many implementations as there are people / teams that wish to implement it. Pugs is a Haskell implementation-in-progress. Rakudo is an implementation-in-progress on top of the Parrot VM. One would expect a JPerl6 and an IronPerl6 too, eventually.
