A sorted map in addition to a hash map would be good, and for a set, both a 
sorted and a hash variety woud be good. And of course, multisets and 
multimaps would be useful too. We also lack a doubly-linked list.

I do agree with others that a normal stack and queue are either unnecessary 
or that they should be achieved via aliasing or some other thin wrapper. 
Creating a whole new container just for a name seems a bit silly and creates 
more code to maintain.
