Perl 6 is finally coming within reach. This article gives you a tour of the grammars and regular expressions of the Perl 6 language, comparing them with the currently available Parse::RecDescent module for Perl 5. Find out what will be new with Perl 6 regular expressions and how to make use of the new, powerful incarnation of the Perl scripting language.

After dissing REBOL for 5 years, they find something worthy of imitation.
“After dissing REBOL for 5 years, they find something worthy of imitation.”
this is too similar to “we have done this before with lisp” thread. who cares?.
Perl has always borrowed ideas from other languages. Sure, the new regular expressions are similar to the parse dialect, but they actually improved on it in the translation. As a REBOL programmer (among other languages), I don’t mind this at all. Perl 6 also borrows heavily from Ruby, Icon and several other languages, as well as the languages that Perl 5 and before borrowed from.
As for who cares, I do. Perl 6 is finally shaping up into an acceptable language – I don’t consider any prior Perl to be so. I look forward to seeing how it develops.
