Hi,
How does Sage solve the following situation? A user stores objects pickled
in Sage version X.1. Then a developer changes internal logic and data
structure of the class of the objects for Sage version X.2. If we assume
Hom(X, Y) is always a set, calling it a homspace seems (to me) to
imply some more specific kind of structure, for example (but not
necessarily) a vector space. It's nice to always use the same term
everywhere for consistency. Homspace is a lot less common:
No, comparison of colors has simply never been implemented. Should be
