What I would next *like* to do is something like the following:

The problem is that there's already a more general instance of
GMaps -- families of map implementations indexed by the key type --
are an example on the wiki:

I've been using something like this myself. It sure would be nice to
have a fully developed version on Hackage, and I may try to submit
this
