How do you make a std::set of structs, pairs, or tuples?
Maybe it was already said (didn't read the whole thread), but I thought I'd add my 0.02$.
I think we should not define meaningless operator< for the structs/whatever, and let the user define one if he wants to use those structs in a set.
We could maybe also do some template / macro fun to help them to define those ? Something like : [TRUNCATE the problematic example macro/function]
If the user has to define his/her own criteria, why can't they just encapsulate it in a custom class they use with a set? They don't have to define it as operator "<", which could have longer-reaching consequences. You do waste keystrokes, but there's no difference computationally (besides avoiding the ADL issues that operator "<" could bring). -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com
