Antoine Pitrou  added the comment:

It seems the revert was not done properly: it removed from 3.10 some bugfixes 
that had been applied to 3.9 (see issue42248 for an example).

[issue44559] Enum: revert to 3.9

New submission from Ethan Furman :

>From the SC (was Re: Enum -- last call for comments on 3.10 changes)

> The Steering Council discussed this topic at our meeting yesterday.  We have 
> some
> discomfort about the changes to Enum’s str and repr in Python 3.10, both in 
> the
> specific changes and in the way the changes were decided on.  No knock on 
> Ethan or
> others who participated in those decisions, it’s just that to us, the changes
> cumulatively feel like they need a more formal, centralized discussion to 
> understand
> all the issues in detail.
> 
> While we’re stopping short of requiring it, the Steering Council strongly 
> suggests that
> for Python 3.10, the changes in Enum’s str and repr be reverted back to the 
> Python 3.9
> behavior, and that a PEP be written for Python 3.11.

The changes were primarily spurred both by the changes to re.RegexFlag and by 
unfortunate choices made in enum.Flag regarding aliases and iteration that were 
corrected.

Unfortunately, it proved too difficult to revert the Flag repr() while keeping 
the corrections, so the entire enum module is being reverted to its 3.9 version.

All the bug-fixes, performance improvements, and other enhancements will have 
to wait for 3.11.
