Oh, yeah, I don't think it would be at all worth the trouble to implement lexical scoping in bash. My point was, that if you *don't* implement lexical scoping, you're pretty much guaranteed to get the sort of conflicts between purposes that the original message points out. And it seems that the best choice in that conflict is the current behavior. Dale
