This half-day tutorial will show you how to use the new pattern-matching and grammar features of Perl 6...in Perl 5.

The first half of the course explains the new regular expression syntax, demonstrating how to convert real-world Perl 5 regexes to Perl 6 syntax, and how to incorporate the resulting patterns into actual Perl 5 programs (via the new Perl6::Rules module).

The second half of the course provides a brief introduction to grammar-based parsing techniques in Perl 6, with working examples including: how to process structured expressions (e.g. search engine queries); how to separate the code and comments in a C program; how to detect overlapping matches in DNA sequences; and how parse ambiguous natural language data.
