Why was I thinking "bi-directional graph"?

Anyway, I would also love to see something like that (now that I realize
what you were talking about).
Maybe more along the lines of the more generalized cases that people are
saying.  I believe that in the past, I've wanted to have 2 different
keys for the same data... A bi-directional map seems like it would be a
good specialization to have since like a map, a bi-directional map seems
like it would be a more common case.  I wouldn't want to stop at just a
bi-directional map though.
