use Perl

Yeah, it's been years since we see something cool like this being done in Perl. Hope DDG can be more popular in the future! I'll be trying it myself.

This opens up many possibilities like generating codes for form validation/processing, command line "usage", etc all from signatures. Btw, is it possible (or are there plans to make it possible) to embed a description/note to each parameter?

Git still has problems being Windows friendly

Not necessarily a problem for everyone :-) You can't totally blame the original designer if he exploits characteristics of a certain OS to gain speed. After all, being cross-platform is not the top design goal for git.

Another example: use many 'A::B::*'; . Having to require '/somedir/*.pl' comes up from time to time for me, though quite rarely.

Actually I kinda like it since I hate all repetitions/duplications and regard them as evil.

But it needs the simplest syntax possible to avoid burning extra brainpower. Somehow all the above examples don't cut it.

How about supporting Unix shell's feature? And how about the name multi or many? use many 'A::{B,C}::{D,E}';

Actually, what I want from Rakudo right now is just more speed (like 10-100x the speed it is now) so I can run it and crash it faster/more often :-). I guess to be comparable to Perl5 we need like 1000x times the current speed, but I'm willing to settle for less.

As a user (i.e. not a parser writer) I still very much prefer YAML over JSON most of the time due to it being more readable.

But yeah, unfortunately many of the earlier Perl YAML parsers do not behave in a standard (YAML-ish) way, not to mention used to crash a lot too.

For YAML::Syck, there's $YAML::Syck::ImplicitTyping = 1; which IIRC was turned on by default in some previous release but then Audrey reverted it back to 0 to avoid compatibility break.

How about everybody just use YAML::XS, then?

Makes me thankful there's Rakudo/Perl6, in which none of this is necessary.

Nice. Ever since I learnt Ruby I'm kind of envious that it has a .sort_by method whereas in Perl we have to do fleshed-out Schwartzian transform. This will make me feel at home again in Perl :-)

I personally don't have a problem with the usage of [] (and remembering the recent PHP \ namespace separator "fiasco" :-) ...)

Hopefully with Perl 6's mutable grammar that Larry et al envisioned, you will be able to change the syntax. Of course this is not yet implemented in any of the current Perl 6 implementations.
