I'm assuming you don't have any class definitions (or declarations) in any
of your builtins. If you do, then this is something like expected
behavior, since classes aren't at all implemented.

This seems more likely -- that it's mis-parsing something as a class def
(though how it does that is beyond me). If you suspect a parsing bug,
it's best to fire up the parser in interactive mode with
perl prd-perl6.pl [--help]
which will spit out parse trees before doing the context stuff.

Bring it on.
