`math.exp` and `math.log` delegate to `__exp__` and `__log__` methods?

For instance, if X is an object representing a normal random variable, it will support operations like 3*abs(X)**2 + 1; the resulting random variable follows a shifted scaled chi-squared distribution with one degree of freedom.

I searched within this thread but found no occurrence of keyword “defer”. I am not sure if I understood OP’s problem correctly, but the defer object idea I’ve been working on might solve this problem from a completely different angle:

>>> from random import random
>>> X = defer.Mutable(random)
>>> 3*abs(X)**2 + 1
