Right, "in" is a set operator. You can implement a set as a dict
with null-values, then you can think of the keys as values. If
you think of the ADT as the set-concept then what is a key and
what is a value is a matter of interpretation. If you think of a
binary tree (or rbtree) as a set, then the distinction between
key and value becomes blurred.
