On a slightly more serious note: That construction is analogous in some way to this one: my $x = $y || $z; # Use TRUE value or default value. But it is harder to describe: my $x = $y && $z; # Replace TRUE value by specified value. So I prefer the Rosler Replacement -- which Rocks! -- You must Sign in before you can post messages.
