Maybe; maybe not. The built-in dispatch mechanism uses a selection
scheme that applies a sequence of increasingly restrictive, but also
increasingly costly, tests; basically, the tests in order are: (1)
identity; (2) isa? (3) model? (is this value a map and are all its
keys members of one or more test maps) (4) = (5) an arbitrary user-
supplied test. A fuller implementation should probably provide the
option of replacing that dispatch algorithm with one of your own
choosing, probably as an option to make-generic-function.

I have given it zero thought.
