For the sake of completeness (by no means something that needs to be
changed now that the patch was merged), ``isinstance`` supports
disjunctive "tuple of types" argument.  Instead of:

    for t in NOTYPES.itervalues():
        if isinstance(obj, t):
            return ...

You can say:

    if isinstance(obj, tuple(NOTYPES.viewvalues())):
        return ...

Cheers,
Fraser
