Are there use cases where the set of keys and the set of values is

In most cases you can probably get away by not offering an "inverse"
object at all, just let regular lookup fall back on value lookup.

hmm, interesting. my use case at hand is mapping color name strings to RGB values -- it should be a one to one relationship, and I need to look for either one.

But you are quite right, they would never overlap, unless someone decided a nice name for a color would be "(125, 15, 235)" -- even then they wouldn't because the RGB value sare a tuple, not a string.

So that may be the way to get the easiest interface.
