Just calm down.. ok if he did spam, he probably was not aware of your reaction... was some joke ok. let it be.

and besides im still figuring out what the poster said with "This behaviour leads into ugly if-else blocks with code duplication."

code duplication what he means? and how come it executes?
was it supposed to stop on the first condition if ent!=NULL and not check the rest ..or is something different.. im just not getting.

I never though about such situations...
