Comment (by tscrim):
Hmmm....that's an interesting way for an unhashable to be obtained and
shows what I get for only testing by explicitly constructing the inverse
map and passing that in. I've moved the logic for determining an inverse
map when none is specified into the appropriate classes, so it should work
now.
