I don't need to be lectured by a lesser programmer, I know what the software I use does, and how well (or not in the case) it does what it's meant to do.
Well I don't know EXACTLY what it is, but all I can tell you is it generally slows down your programs execution times (only a little, but hey) but I guess it's useful.
As a lesser programmer, I will not try to influence your oppinion any more. It's already set, based on solid information and a infailable judgement. I bow before you.
