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.
