Comment (by nbruin):
Do you have a reason to make `domain` and `codomain` cached? Their
implementation already consists of just an attribute lookup. Are you
getting a performance increase from it? There definitely are drawbacks:
- the method gets wrapped, so there's extra junk sitting in memory for
that
- the cache takes up memory for an attribute that's already there anyway.
