in thread Toggling between two values

Your "closure" sub isn't actually a closure; to be a closure it would not only have to access outside lexicals (like yours does), but also be anonymous.
No, "closure" and "named" are orthogonal properties. In the following, the named subroutine gimme is a closure:
BEGIN { my $number = 0; sub gimme { ++$number; } }
Yes, there's some Perl literature that mixes up the two concepts of anonymous and closure because they are often correlated, but really they are separate properties.

Although I do feel a bit weird correcting chip on this point. {grin}
