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.
