I've put together a draft with my ideas and design for (re-)implementing lexicals in Parrot -- now available at http://www.pmichaud.com/perl6/lexical.txt .
It's a first draft and might be a bit confusing in places, but overall I think it's a far cleaner design than the current implementation but also handles the vast bulk of what we need (or can be made to do so easily). Anyway, comments greatly appreciated. Pm
