One thing that might make this easier would be a collection of collections
type:
Many!(T, RBTree, Array) foo
foo would have the API for both RBTree and Array but adding/removing to/from
one would also do the same to the other. This might be more useful with something
like several RBTrees where each is sorted differently.
