I have been noticing the ? used quite a bit, and I don't know what it does. I know in
regular expressions it means 0 or 1 but what about in a time like:
for my $op ( and, or , xor ) {
print 0 $op 0 , eval 0 $op 0 ? TRUE : FALSE;
print 0 $op 1 , eval 0 $op 1 ? TRUE : FALSE;
print 1
Have a look to this :

I have been noticing the ? used
more simply as:
$a += ($a % 2) ? 10 : 2;
