There are no unbound methods in Py3k, but pure function instead. That
would make the issue even easier. There could be @callableproperty
decorator for such cases. I'd +0 on such an idea.

Maybe better idea (if we want to avoid missed-parenthesis-mistakes)
would be to raise an error when trying to test such functions/methods
for truth. I could be achieved with a subclass of function type with
__bool__() method raising TypeError or NotImplementedError.
