jrsmith has asked for the wisdom of the Perl Monks concerning the following question:

is it bad form to leave off the else in if statements if you are not going to use it? just something i'm pondering..
like this-
if ($x = $y) { print "$y = $x\n"; }
instead of-
if ($x = $y) { print "$y = $x\n"; } else { #waste of space }
