Well, from a coolness aspect, it's quite reasonable, however, I think it suffers weakly from a maintainence aspect, in that others that may not be ask skilled in perl will be confused.
OTOH, ||= is very cool, and maintainable, in using it to set default values when none are provided:
sub mysub($$;$) {
my ( $a, $b, $c ) = @_;
$c ||= 3; #c is 3 if not already defined
}
(Of course, this assumes that the value on the left is in some 'error' state if it's zero or undef.)
Not that &&= doesn't have it's usefulness while being maintainable, eg:
my $flag = 1;
foreach (@item) {
$flag &&= usable( $_ );
}
print $flag ? "All usable" : "not all usable";
