in reply to Perl Style: Is initializing variables considered taboo?

If the undef has a significant meaning, I define it explicitly to make the code as clear as possible. Otherwise, I spend my keystrokes elsewhere. For example:
my $found = undef; foreach my $candidate (@candidates) { if ( good($candidate) ) { $found = $candidate; last; } } if (defined $found) { print "Found a good candidate: $found\n"; }
