# User-defined methods, both instance methods and class methods, can be called in many non-standard ways
# i.e. differently from simply `c.f()` or `C.f()`. For example, a user-defined `__await__` method on a
# class `C` will be called by the syntactic construct `await c` when `c` is an instance of `C`.
#
# These tests should cover all the class calls that we hope to support.
# It is based on https://docs.python.org/3/reference/datamodel.html, and headings refer there.
#
# All functions starting with "test_" should run and execute `print("OK")` one or more times.
# This can be checked by running validTest.py.
