in reply to Parsing with Perl 6


Thanks for the more complete writeup of the new regex syntax and semantics. I found it difficult to get a "big picture" idea of how things are expected to work from the Apocalypse, even though that made for some excellent reading. This should keep me satisfied until Exegesis 5 comes out.

I'm going to be very interested to find out how well these grammar-based regular expressions play with Perl 6's increased focus on functional and logical programming (or at least my perception of increased focus). In my admittedly limited experience, thinking in "functional" terms, in "logical" terms, and in "grammar" terms require similar mindsets and methods of reasoning, and I hope that the Perl 6 developers can unify (heh) these facets of the language.

Update: For instance, there are a few hints on about the Perl 6 parser being retargetable, mungeable, and tied in with the regex engine. With luck, this'll make it easier to treat code as data, which seems to have worked out fairly well for Lisp. (And I'd love to see it in Perl, despite the fact that dealing with Perl code is a much hairier task than dealing with a bunch of (possibly nested (like this)) lists.)

The hell with paco, vote for Erudil!
