I thought I'd have a go at command-line parsing (http://perlgeek.de/blog-en/perl-6/contribute-now-main-sub.html), and I've got the basics, even though I keep trying to put P5isms in my regexes! (I even found a bug, but it's already reported, RT 73608.)
I wanted to check that named regexes aren't in Rakudo yet -- I get "Useless declaration of has-scoped regex in a module". -David
