Note that my patch adds an optional argument "name" to the cached method decorator. So, your work-around is easily possible with my patch: sage: class A(SageObject): ....: @cached_method ....: def toto(self,arg): ....: return arg+1 ....: sage: class CC(A): ....: toto_cached = cached_method(A.toto.f,name="toto_cached") ....: def toto(self,arg=2): ....: return self.toto_cached(arg) ....: sage: c = CC() sage: c.toto() 3 sage: c.toto() 3 sage: c.toto() is c.toto() True However, it is a work-around and not an actual solution, IMO.
