Hi, I vaguely recall that PEP 617 "New PEG parser for CPython" was supposed to deprecate the lib2to3 module and the 2to3 program. I see that lib2to3/__init__.py contains a PendingDeprecationWarning in Python 3.9. Can it be converted into a regular DeprecationWarning and document the deprecation in Doc/library/2to3.rst? -- Do we still want to maintain lib2to3? People who didn't migrate to Python 3 can use 2to3 of Python 3.9 or Python 3.10. There are also other tools like 2to6, modernize, etc. (or my "sixer" project which I no longer maintains.) I'm not sure sure if the lib2to3 module is used by 3rd party projects like modernize or black? I understood that lib2to3 is a LL(1) parser and so cannot be used with latest Python grammar. Well, also, Python 2.7 is not longer supported. Victor -- Night gathers, and now my watch begins. It shall not end until my death.
