Perl 6 Summary for 2005-01-11 through 2005-01-18
Welcome to yet another Perl Summary brought to you by music and pizza
(although the pizza is late in arriving). Like many summaries before it,
we start with an attempt at non sequitur and Perl 6 Language.
Perl 6 Language
idiomatic Perl 6
Stéphane Payrard expressed a desire for more Perl 6 sample code. Luke
Palmer issued the following, possibly foolish, response: "post some
\"how do I\"s to the list, and I'll reply with code". Austin Hastings
posed a couple, not response yet...
<http://xrl.us/er2z>
generalized tainting
Yuval Kogman posted an interesting musing about contagious properties
(if you get your value from someone with a contagious property, you get
the property too). No responses, but it sounds interesting...
<http://xrl.us/er22>
stick/pick
Richard H. suggested a new pair of functions stick/pick which would have
modifiers such that push, pop, shift, unshift, and splice could all be
calls to stick or pick with appropriate modifiers. Unfortunately, I
think he posted it to the google groups interface, as it is there but
not on the list :-(
<http://xrl.us/er23>
Perl 6 IDE again.
Matisse Enzer re-raised the question of the feasibility of an IDE for
Perl 6. Unfortunately it was re-raised on google groups (I think).
<http://xrl.us/er24>
1x6 vs 6
The dimension slice issues continue to grind with new suggestions from
David Green and Craig DeForest.
<http://xrl.us/er25>
life span of loop counters
Joe Gottman wants an easy way to restrict the lifespan of his loop
counter to his loop. Some folk (myself included) did not like the answer
of wrap it in a scope. Some others (myself excluded) thought the answer
"don't use loop, use for" was a bit of a cop-out.
<http://xrl.us/er26>
forany & forall
Jonathan Lang wondered how to check if a condition is true for any
element of an array or for all elements. The answer are the aptly named
junction creaters "any()" and "all()".
<http://xrl.us/er27>
Perl 6 Compiler
Already reached p6c and no pizza :-( Ah well, it was a light week.
Parrot Internals
Already p6i and no pizza :-(. Although it was close, after I wrote the
head2 my door buzzed. It was just a neighbor who got locked out, but
that would have been impressive timing.
blib in 25 seconds
Peter Christopher asked for a 25 second summary of the ./blib directory.
Apparently this is harder than Hamlet in 30 seconds, as one of the two
has been done.
<http://xrl.us/er28>
searching archives
Peter Christopher wanted to know if there was a way he could search the
mailing list archives. Steve Fink pointed him to groups.google.com and
the ever popular discussion topic "aardvarks".
<http://xrl.us/er29>
dynclasses with external dependencies
Bernhard Schmalhofer wondered if there was a reasonable way to check for
external dependencies for dynamic PMCs that does not involve the core
Parrot configure step. Later he supplied a patch with his GDBMHash pmc,
which motivated the question. Leo applied it and hinted at a mythical
multi-stage configure
<http://xrl.us/er3a> -- question
<http://xrl.us/er3b> -- patch
s/interpreter/INTERP/g
Bernhard Schmalhofer provided a patch making the above clean up all
over. Leo and Sam applied different parts of it.
<http://xrl.us/er3c>
black-ops parrot
Robert Spier posted a link to the new listing for Parrot on CIA.
Nicholas Clark dove for cover assuming he was going to be disappeared.

actual post
PDD problems on the website
Dave Brondsema noticed that PDDs 4-6 were not finding their way to the
website properly. Will Coleda fired off a patch.
<http://xrl.us/er3e>
cleaning old tickets
Will Coleda, in his never ending role as RT janitor, closed out a few
obsolete tickets. Thanks Will.

Scope and Timely Destruction
Leopold Toetsch raised the recurring issue of timely destruction. It
turns out that timely destruction is hard. Various people made various
suggestions. Let me state one thing clearly as if I don't, Dan doubtless
will: Parrot will NOT use reference counting of any kind. There are a
great many reasons for this some of which Luke Palmer explained.
<http://xrl.us/er3i>
ParrotIO* should have been PMC*
Peter Christopher provided a patch fixing a pointer declaration bug. Leo
applied it.
<http://xrl.us/er3j>
questions for the compiler FAQ
Some time ago, a compiler faq was started. It was to contain answers to
questions that people posted to the list. Will Coleda posted 2 such
questions, but got Warnocked.
<http://xrl.us/er3k>
languages/perl6
Will Coleda wondered what was going to come of the languages/perl6 stuff
since it now has its own SVN repo. No answer.
<http://xrl.us/er3m>
Parakeet with broken wings
Will added an RT ticket for Parakeet which got broke in the shuffle.
<http://xrl.us/er3n>
crashing parrot
Will found out that he could crash parrot by doing stuff with GCed
memory. Leo admitted that one could.
<http://xrl.us/er3o>
collecting academic garbage
Shevek wondered if there was a good place where he could read about
garbage collection techniques. Garrett Goebel pointed him to just such a
page.
<http://xrl.us/er3p> -- the post
<http://www.cs.kent.ac.uk/people/staff/rej/gc.html> -- the page
argv[0]
Will wants to get at the moral equivalent of argv[0].
<http://xrl.us/er3q>
proposed VTABLE changes for method lookup
Leo suggested a VTABLE change to facilitate MMD and method lookup.
Suggestions and questions were provided.
<http://xrl.us/er3r>
food
Matt Fowles's pizza arrived. The reader then speculated that either (he
writes slowly or it arrived quickly) or (he writes quickly or it arrived
slowly), depending on various readers estimates of Pizza delivery time
and expected word per minute summarization.

bring hither the fatted parrot
Dan has returned to us. Hopefully he will be able to advance the quest
for meta-objects and interoperability.
