Saying that no one uses closures intentionally is wrong. I use them
extensively... intentionally... and successfully.
Josh is talking about named subs, not closures. When Josh said that
they create closure issues, I believe he was referring to the lexical
scoping issues surrounding using subroutines defined inside
subroutines that can be very confusing to those who don't have a very
firm grasp of the Perl language (and sometimes to those who do ;-)).
Well, I did not wrote this - but I meant this :-) (At least I hope ;-))
