Two methods in schemes/generic/homset.py contain a comparison 'R == Z' instead of 'R == ZZ'.

Fixed by #11526.

Apparently this was introduced in [changeset:15345:08d4a1aad8b5].

About the doctests, could you provide some example which triggers the bug? We could probably use that for the doctest.

I changed the #11526 patch to also fix the typo in the projective case.

Replying to @saraedum:

Oops. Should have read what was written in the ticket. Setting an author here doesn't make much sense.
