This module defines functions for checking object types (check_type()) and subclasses (check_subclass()). These functions take the same arguments as isinstance() and issubclass(), respectively. This is normally useful in functions where we want to enforce argument types. Example usage:

from rr import typing

typing.check_type(3, int)
typing.check_subclass(list, object)

Developed and tested in Python 3.6+. The code may or may not work under earlier versions of Python 3 (perhaps back to 3.3).
