I'm glad to see more people trying Perl 6 via Pugs! I think the more advocacy and discussion we can generate -- such as Limbic~Region has been doing -- the better it'll be. That being said, I have a comment about your specific post:

This would probably be more useful if it had equivalent Perl 5 code to compare to. A table with two columns would work very nicely, except some of these snippets are a bit long for that. Perhaps that should be a clue to shorten the long snippets, to reduce them to bite-sized chunks.
