Re: Program unsuspectingly dies with no reason why.

It might have something to do with the line &clean_the_file(); The & denotes a function reference, but you're not calling the function via a reference. If you use clean_the_file(); I think it'll take care of the issue.

Update: Never mind, I'm a loser.

Errm, no. Something like `\&clean_the_file` would be a reference. While calling subs with the leading sigil does have an effect, it's not going to stop `&clean_the_file()` from being called in any sane circumstance. See perlsub. (Of course if someone has created just such a circumstance then they deserve what they get for using prototypes where they shouldn't :) The cake is a lie. The cake is a lie. The cake is a lie.

Actually, `&foo()` is a call to the sub `foo`. To take a reference to the sub, use `\&foo`. `sub foo { print "foo: ", $_[0], "\n" } &foo( 'called with &' ); foo( 'called with no &' ); my $foo_ref = \&foo; $foo_ref->( 'called via reference' ); &$foo_ref( 'called via & and reference' ); __END__ foo: called with & foo: called with no & foo: called via reference foo: called via & and reference` [download] The only special thing about `&foo()` vs. `foo()` is that the former will disable any prototypes the sub may have.
