Comment(by SimonKing):
At [http://groups.google.com/group/sage-
devel/browse_thread/thread/c62fa3dae0a2ca82 sage-devel], Maarten mentioned
that pickling does not seem to work for the code posted here, which seems
to be due to some attributes typically involved in coercion.
Looking at [attachment:trac_9054-all-parts.patch], I see that the base
class for function fields is derived from `sage.rings.ring.Field`, but
`Field.__init__` is not called.
The rings in vanilla Sage do not pay enough attention to coercion and
categories. #9944 and (in particular) #9138 aim at improving the
situation. In particular, with #9138 it should now possible to avoid any
direct call to `ParentWithGens.__init__`; calling `Field.__init__` should
just work (tm). Can you try?
