cpython/Lib/importlib/test/test_abc.py
Brett Cannon 2a922ed6ad Introduce importlib.abc. The module contains various ABCs related to imports
(mostly stuff specified by PEP 302). There are two ABCs, PyLoader and
PyPycLoader, which help with implementing source and source/bytecode loaders by
implementing load_module in terms of other methods. This removes a lot of
gritty details loaders typically have to worry about.
