in thread Can you guess the result? Is it a bug?

The warning is just trying to help you out so that you don't have an if that evaluates to a constant boolean value which these all do. Consider:

... if($val == 3); #versus ... if($val = 3);

In the first is checks to see if $val is 3 and in the second it sets $val to be 3 and then checks $val for truth which in this case is always true. So for normal situations that line should just be:

...; $val=3;

Which would have the same effect in my little sample program.
