Not always. For example: If you have a cached method (such as groebner_basis of multivariate polynomial ideals) then you want to see the documentation respectively the code of the underlying groebner_basis method, but not the doc/code of sage.misc.cachefunc.CachedMethodCaller (which is the actual class which groebner_basis is instance of). > For your two concrete proposals: > > Does that mean extra slots on Parent and Element? I don't know if it could be called a "slot" (if I am not mistaken, that's a technical notion). But yes, it would involve a new cdef attribute. > In that case, -1.

For the record: I did not claim that my two suggestions are good suggestions. But I did not see another way of providing a *general* framework for providing instances (not sub-classes!) with a custom doc string.
