Let me also add Rebol into the mix. To quote Carl Sassenrath... Every time I run across JSON examples, I see REBOL without the elegance. The two languages are related of course. REBOL strongly influenced the design of JSON. ref: On JSON

I think S-expressions would have been better. Alternatively Carl Sassenrath was pushing Rebol in the past. See his blog post "Was XML Flawed from the Start?" - http://www.rebol.com/article/0108.html Update:

A bit of apple & oranges going on here because you don't need Moose (or more precisely Class::MOP) to simulate Python metaclasses and descriptors. Because you could, if you so wished, build a Python metaclasse/descriptor bas

Nope. * Some of the best languages for producing an internal DSL (dialects) don't have a "native MOP". For eg. Lisp, Rebol or Forth. * Python & Ruby don't have native MOP's anyway :) NB. I wonder what you mean

The full statement from the article was - Rebol and Red, whose open source implementations are still very immature To clarify this… 1) Rebol 2 is a very mature product. But while free to download & use it remains closed source with no

Yes that's correct. Atronix efforts have been towards producing 64-bit versions + the Linux GUI from the Saphiron code base (which was 32-bit and Windows GUI). Here's the Atronix announcement - http://rebol.info/

You can write more verbose regex using Named Capture Buffers. Here is an example I posted on HN not long ago: https://news.ycombinator.com/item?id=6895126 NB. Follow link to original post to compare against standard reg

My first opensource creation was a port of Jim's wonderful Builder gem. Many thanks Jim for the inspiration you'll be sorely missed.

What most programmers today call a DSL are in fact just an API anyway!

Having something like CL Condition System in Perl6 would be very nice! I've only seen the try/CATCH stuff. Are there any examples of restart/resume/continue handlers ala CL? BTW: Here's the Perl5 Condition Syste

It's only a surprise if you don't understand it. Every Perl programmer needs to fully grok and embrace it because it's a core language feature. For others, this is what EdwardDiego is referring to: my %hash = (a =>

If it had been written in some other scripting language then I'd guess you would have had even more issues upgrading! Because Perl, despite all its supposed warts & bad image, remains highly backward compatible. NB. The biggest

And you can also do that in Perl: set_timeout sub { __SUB__->() if should_recurse(); }; NB. __SUB__ was added at Perl 5.16 and so requires either: use 5.016; # or newer use feature 'current_sub';

I prefer to counteract these potential bugs by locking the keys of a hash. For eg. in Perl: use Hash::Util 'lock_keys'; my %hash = (key1 => 'foo', key2 => 'bar', key3 => 'baz'); lo

It definitely would be beneficial if it were on CPAN. However they would need to add tests to the repo first :)

Tk was very handy for whipping up GUI apps. However those comparison examples written in Perl (not Pearl!), Ruby & Python could be improved to look (at least a little!) better. For a completely different comparison (non Tk) here is the

I think if prodigal_erik is worried about autovivification then perhaps locking the keys might be a good idea?... use 5.016; use warnings; use Hash::Util 'lock_keys'; my %a = (B => 100); # B but no A defined l
