Meh, I just remembered that I tried this. The current implementation requires
that the "name" value be a literal string object (or at least something
convertable to Unicode). I think we could relax this requirement; it really
only needs to be hashable. I wouldn't want to deploy the API if the keys were
required to only be strings.
