I actually feel pretty stupid for not seeing that. It's quite simple, really: rather than making the current buffer a package variable on the buffer class, I just make it a method (that functions as an lvalue if need be; I'm pretty sure that's possible in Perl6) on the buffer class, and then I can do whatever symbol table changes I need to do. It makes changing buffers very frequently a little more inefficient, but it won't be a big deal unless you have a lot of buffer-local variables, and in that case it's worth it because you're really using the feature. And actually, it's probably not less efficient than making every variable lookup check for buffer-localness.

I'm happy. Perl6 is going to be so cool. Here's looking forward to the next Apocalypse :-) 

for(unpack("C*",'GGGG?GGGG?O__\?WccW?{GCw?Wcc{?Wcc~?Wcc{?~cc'
.'W?')){$j=$_-63;++$a;for$p(0..7){$h[$p][$a]=$j%2;$j/=2}}for$
p(0..7){for$a(1..45){$_=($h[$p-1][$a])?'#':' ';print}print$/}
