Great, thanks for making all these changes.

What's the meaning of "It is an error if the members of the result do
not all belong to the same enum type" in the context of enum-set-delete!
and enum-set-delete-all!?  These procedures don't add any elements to
their enum-set arguments.  Is it expected that these procedures will
also check this set argument for consistency?
