Concerning the ABC module: It seems to be the correct way to do what we are doing now with all the `is_Whatever` properties.
obj.is_Whatever == True -> isinstance(obj, WhateverABC) All the automatic correctness checks for "virtual" methods are nice as well. Moreover mpmath has a barebones support for ABCs for some months now. -- You received this message because you are subscribed to the Google Groups "sympy" group.
