in thread Or, Or, Equals Zero, $x ||= 0

If it's on a new code, and no animals are harmed, I don't see a problem with using 5.10 syntax. It's a question of what the people around you like to read. For instance, I'd write it
$x= '' unless defined $x;
But its a question of whatever suits.

Software speaks in tongues of man; I debug, therefore I code.
