An ordered map is a foundational data structure as opposed to, say, a
priority queue, let alone something like urllib2.

If I had to choose between a hash table and AVL (or RB) tree in the
standard library, it would definitely have to be the latter. It is more
generally usable, has fewer corner cases and probably has an equal
performance even in hash tables' sweet spot.
