You can find more information on the speaker's site:
One of the coolest features of Perl 6 is its regular expression syntax, which not only does traditional pattern matching but is also expressive enough to support grammars and advanced parsing. Indeed, it's the core for writing parsers with the Parrot Compiler Toolkit.
This talk provides an exploration of Perl 6 regular expressions. It describes how they are currently used in Rakudo Perl and Parrot, and how they may be used to write parsers and as the foundation for more advanced data translations.
Topics include:
* Basic regular expression syntax
* Named subrules and captures
* Regexes, tokens, and rules
* Creating grammars
* Attaching actions to regexes
* Processing parse trees
The presentation will include numerous examples that work today in Rakudo Perl.
