One problem in C++ is if you define a struct then you have to define a bunch of operators yourself (operator<, etc.) which gets annoying after you've realized you've needed them a bunch of times.

Does C++ Pair<> define operator< and operator>?

That's surprising, and for me looks completely uncalled for.

EDIT: Just looked into Haskell (because it's easier), and tuples do derive Ord there. Is there some universal convention I'm missing?

Tuples are always compared lexicographically, is the universal convention. Not sure if that's what you might be missing?

It does.

std::sort(pairarray.begin(),pairarray.end()) works about how you'd expect, as long as operator< is defined for the constituent types of the pair.
