Really? That sounds unjustified outside of some specific context. As a general rule I just can't see it.

I don't see whats fundamentally wrong with it. Whats the alternative? Multiple static functions with different names corresponding to the flags and code duplication, plus switch statements to select the right function?

Or maybe you're making some other point?
