If we implement sets using balanced trees, then we can support the natural
tree orderings like in-order. These are very natural choices. But here the
ordering is on the keys, and I don't think we always have well-defined keys
unless we ask the user to provide one...

I also want to suggest that we allow multiple implementations for the same
ADT. For example, the default dictionary implementation could be red-black
trees, but programs with good temporal locality can use a dictionary based
on splay trees. This also allows us to plug in new implementation later if
needed.

I guess it is not difficult to design it with enough flexibility so that the
user can decide what "equality" means. I would imagine that most of the time
users would want value semantics and so they will define their own equality
function to say when two objects have the same value.

Just my 2 cents.
