It was nice actually *meeting* some of the people that I've been interacting with since beginning working on/targetting parrot several years ago.
It's too bad that Matt Diephouse couldn't go - I suspect we'd have been able to advance partcl quite a bit.
Matt's currently working on a patch to improve list to string shimmering, which should raise our test percentage quite a bit.
I'm working on updating [expr] handling. When I started writing this, parrot was in its infancy - the only real way to write a parser was to do it externally (and I didn't want to introduce any external dependencies), or by rolling your own in PIR or C: so I rolled my own parser.
With Patrick Michaud's latest work on PGE, however, it looks like I'll be able to rewrite these bits into a Perl 6 grammar. I'm in progress on this, though after 3 days in Toronto, I have some real work to get done first. ^_^.
