Python3.11 - importlib no longer exposes .util

[DavidCEllis (David Ellis)]

Currently, importlib.machinery is in sys.modules at python startup even though it does not appear in importlib.init and likely was imported by something else. Perhaps importlib.util was once similarly present at python startup.

This is true in the REPL as rlcompleter is imported and depends on inspect which depends on importlib.machinery. However it’s not generally true that it’s imported on startup.

$ python -c "import importlib; importlib.machinery"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
AttributeError: module 'importlib' has no attribute 'machinery'
