Documentation? Tests? Remember the disaster with the perl6-documentation list? We couldn't even get basic literals documented due to a lack of any solid information source. Code? Bug Reports? Patrick and Luke are designing and coding off-list and off-cvs.
Sure, a lot of the people who complain are just a bunch of whiny jerks. But if you're not interested in parrot itself (the compiler, regex engine, documentation, tests, builtin-functions, core classes and libraries), there really isn't a lot that a non-cabal member can do for Perl6.
