[New-bugs-announce] [issue45540] module.__package__ and module.__spec__.parent have different semantics

[Barry A. Warsaw]

New submission from Barry A. Warsaw <barry at python.org>:

TL;DR module.__spec__.parent is read-only but module.__package__ is r/w despite documentation that implies that these two attributes should be identical, and various issues that focus on migrating from direct module attributes to ModuleSpec attributes.

bpo-33277 and bpo-21762

Maybe we should relax the restriction on module.__spec__.parent so that it's writeable just like module.__package__.
