Do you think it was a cocky attitude because of my "no, thanks" sentences? I can't understand why. It's just a different interpretation of yours, maybe of the whole post, because I didn't feel anything bad like that while typing (here I generally don't), meaning I couldn't intend to be cocky, so there's nothing I can do. Anyway, sorry. But if you want to continue on this subject, here's not the place. Let it be private.
About the main subject, whatever, I'm not into posting big varied examples of where the "if crap(?)" would be needed in such a de-centralized way of grouping, when a lot of relevant points are already there IMO, that's enough.
