Good question.
I guess in CLOS, this works by creating a new class that derives from
the standard "generic function" class, then make your generic function
be an instance of *that* class, at which point you can then define your
`cl-no-applicable-method` method which specializes on the class of the
`generic` argument.
But currently cl-generic does not support this notion of "generic
function" quite the way CLOS does (for one our "generic functions"
objects are `defstruct` rather than `defclass` objects, and also
they're not callable so the function cell is yet different (a fairly
standard closure)).
