Python metaprogramming allows type-like things to be bases, not just things that pass PyType_Check(). so being that strict isn't going to work. The other classic way to prevent this is to track what you're recursing on to avoid a loop. i.e. Keeping a set of PyObjects that have been seen and not recursing if the value is in that.
