Typeglobs are on the endangered species list. That is part of the reason
for this RFC.

Aha! You fell for one of my pet pieves. You tried to return a lexical in
the same expression were it was declared. That doesn't work. It's not
the same variable. Running it with warnings enabled says:

   Name "main::fh" used only once: possible typo at test.pl line 3.


I feel that this ought to have worked, i.e. that the scope of the
lexical kicked in in the middle of the expression, at the transition
over the shortcut operator "&&".
