Re^2: Type globs, strict, and lexical variables

Cool! never would have thought I could localize a typeglob itself. Hmmmm... will this really work, since you can't localize a variable that doesn't pre-exist, under strict.

you can't localize a variable that doesn't pre-exist, under strict. That's not true. `strict` has nothing to do with `local`. For example, `perl -Mstrict -e "local $Package::foo"` give no error. `perl -Mstrict -e "local $foo"` gives an error, but so does `perl -Mstrict -e "$foo"` will this really work Strict doesn't apply to globs (since they can't be declareds), so `perl -Mstrict -e "foo"` and `perl -Mstrict -e "local foo"` give no error.

Strict doesn't apply to globs (since they can't be declareds), so
perl -Mstrict -e "*foo"
and
perl -Mstrict -e "local *foo"
give no error.
