turnstep said: Saying 
$flip + 1;

does not change in any way the scalar referred to by $flip, while "++$flip" does.

Yes, turnstep, of course the preincrement modifies $flip.

The question at issue is, "Why do we care about modifying a variable twice?" Simple as that.

Go back and read the post and respond to the actual issue, please.
