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 :

#define DEF_OP_MIN(cont) bool cont::operator<(const cont& a, const cont&b) {
return &a < &b; }
