Isn't this the real issue:def is_VectorSpaceMorphism(x): return isinstance(x, VectorSpaceMorphism) With the category stuff the correct check is whether VectorSpaceMorphism in x.__class__.__mro__. Is there a better way to express this? Whats the ..._with_category class if I want an isinstance() check?
That's how analogous is_* commands are defined, I think. Are you saying that all of them are implemented wrongly?
I think isinstance tests for superclasses too. Is that what you are asking? Notice:
sage: h = (RR^3).hom(matrix(RR, 3, [1..9])) sage: sage.modules.vector_space_homspace.is_VectorSpaceHomspace(h.parent()) True Thanks, Jason -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
