Oh, I see. Just two quick questions:
* will sub definition create globals? I mean, does "sub a {}" create
a function PMC and store it into the "a" lexical? or will there be
a separate mechanism for functions?
* Is there any chance that lexicals get mapped to registers, at least
in the cases where the block doesn't use any dynamic features (MY%,
eval, etc..)?
Thanks.
