Without an argument, return gives the sub's caller either undef or an
empty list, depending upon context. Can you give an example of Perl
code that shows what you're talking about? Here's what I'm talking
about:
sub return_empty {
return;
}
my $scalar_value = &return_empty(); # gets undef
my @list_value = &return_empty(); # gets empty list
What do you do with return that "gives you a zero"?
