gh-82626: Schedule removal of bool used as file descriptor by vstinner · Pull Request #145469 · python/cpython
Since Python 3.13, Python emits a DeprecationWarning when a boolean value is used as a file descriptor. I propose to schedule the removal in Python 3.18 of bool support when a file descriptor is expected. So the feature is deprecated for 5 releases (3.13 to 3.17), as recommended by PEP 387.
