I like the explanation of how Rats solve a class of rounding errors,
0.3 - (0.2 + 0.1) equals exactly 0 for example. On the other hand,
it's still a compromise that's shifting closer to correctness, fixing
a bunch of potential bugs, but not all in that class:

I think Perl 6 tries to include too much rather than too little.

Subsets will be absolutely essential, if it is to be possible to learn
it with a reasonable amount of time and effort.

This is another of my points: when presented with all the features in Perl 6 -
what is then essential?
The essential features - besides being presented up front and center to newbies
- are also good candidates for what should go into the core.
For instance, why have Complex and Rat numbers in

For instance, why have Complex and Rat numbers in the core? If you're
not working in a very specialized field (which probably *isn't*
numerical computation), those datatypes are just esoteric constructs
that you'll never use.
Yes, unpredictable performance is a price I'm willing to pay. I'm using a
dynamic language after all.
If you aren't willing to pay it, just use typed variables. Or even native
types, like num or int. Choose your own number representation -- there's
more than one way to do it.
The design
I like that I can start with a fairly simple subset of Perl 6 but pick up more
as I go along, if it’s needed.

The goal is to avoid everyone using a different not fully compatible
version of everything. Like in perl 5 with the bunch of different ways to
do objects, signatures etc.
Pilling good things on top of each others rather than aiming for an elegant
design is what I consider the core idea of Perl.
Yes. It looks nice that Perl 6 recognizes zero in this way, but the consequence
is that each implementation of Perl 6 has to run a gcd algorithm every now and
then.
I'd be very surprised if the computational complexity of any useful (even
approximate) gcd algorithm doesn't scale with the with

I really understand your point. If there was several competing OOP modules,
things *could* get really complicated (in my opinion, it isn't the case for
perl 5, but it is worth discussing), but it doesn't seem as if anyone has put
any effort into defining what needs to be common and what

Perl6 has something similar to example 9.
Ranges, hyper-operators as well as the invocation operators .+ and .*
doesn't make any sense to me. Those constructs made me stop
