Word ...
From the `cl-generic-generalizers' docstring:
It's called a generalizer because it takes a specific object
and returns a more general approximation, denoting a set of
objects to which it belongs.
Think of the -er suffix, e.g. toaster. It is the thing that
does things. Like MacGyver. A real man of action, right?
