The matrix morphism class implements just __cmp__, with no __hash__. Existing free module morphism class implements neither, my new vector space morphism class implements neither. Free module morphisms behave properly with respect to equality (eg ==), making calls to the matrix morphism __cmp__ in the process. Vector space morphisms can "see" and use the matrix morphism __cmp__, but the == syntax won't behave properly.
