[New-bugs-announce] [issue44471] Raise TypeError in ExitStack.enter_context() for bad argument

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

For consistency with the "with" statement (see issue12022) ExitStack.enter_context() should raise TypeError instead of AttributeError if the argument is not a context manager. Same for AsyncExitStack.enter_async_context().
