That's crazy. If the list is empty foreach still does the right thing
- there's no benefit in guarding a foreach with a conditional.
I don't remember many cases where I wrote something like this:
my $found;
foreach my $item (@items) {
if ($item = 'foobar') {
$found = 1;
last;
}
}
unless ($found) {
..
}
I'd say that or a close variation of it was a pretty common idiom.
