Add helpers for deprecating modules.
Review Request #13014 — Created May 4, 2023 and submitted — Latest diff uploaded
This introduces two new functions for deprecating modules:
module_deprecated()andmodule_moved().
module_deprecated()can be called in the body of a module to emit a
deprecation warning when the module is imported.
module_moved()is similar, but takes a destination module, and points
consumers to that module in the deprecation message.
Unit tests pass on all supported versions of Python.
