a question on style

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
}
