add a BEGIN so that instantion happens at the same time that a named
sub would be:
BEGIN { * foo = sub { ....} }
and the problem comes back ;-)
Anyway, coming back to my original suggestion:
I think closures are a lot harder (or at least subtler) than people
think, and explicit declarations might help. There again, they might not.
Ah well....
