Big +1 from me for at least supporting a way to get the more concise output.
I've never understood the verbosity of python's argparse where the metavar is
repeated.

This would also be useful for me - I just hit this same problem. If someone
could give some guidance on how to make this change I'd be happy to put up a PR.

@Serhiy - Yes, I noted that problem in the PR. Thanks for pointing me to that
issue, I agree it would be good to make pprint properly extensible (my current
solution is to maintain a fork of the pprint module with dataclass support
added).
Eric's suggestion
Lewis Gaul added the comment:
> a dataclass can do anything a regular class can do
Agreed, but isn't that also true of any subclasses of currently supported
types? In particular 'UserDict', 'UserList' and 'UserString', which all have
explicit support in pprint and are intended for &quo

New submission from Lewis Gaul :
Currently the pprint module does not have support for dataclasses. I have
implemented support for this and will link the PR once I have the issue number!

You're right that's how I had interpreted it, thanks for clarifying.
I was wondering if this could be related to an issue I've hit with gc.collect()
getting slower and slower in a test suite, but that now seems unlikely, so I
won't go into that here
Lewis Gaul added the comment:
I noticed this bug is mentioned in the 3.9 release notes with a note similar to
the title of the 4th PR: "garbage collection does not block on resurrected
objects".
I can't see any mention of a blocking issue here on the issue:
> The bug: t
Lewis Gaul added the comment:
It seems that test_audit_subinterpreter() in _testembed.c was
(unintentionally?) doing this already.
After fixing #36225 I found this testcase causes a segfault, but works fine
when switching back to the main threadstate before calling Py_Finalize().
So

The relevant code for the multiprocessing example seems to be in
Lib/multiprocessing/spawn.py. I think I get what it's doing, but I'm not sure
whether we actually need something similar for subinterpreters. Any thoughts
@eric.snow
Lewis Gaul added the comment:
Just to move the conversation from the subinterpreters project repo to here...
I'm going to take a look at how this is done by subprocess using the example
provided by Guido:
import os
from concurrent.futures import ProcessPoolExecutor
from multiprocessing

I've put together a test along the lines of what Nick suggested, see the
attached patch. Running this hits the Fatal 'remaining subinterpreters' error

New submission from Lewis Gaul :
The public interpreters API being implemented for PEP 554 requires the ability
to list interpreters associated with channel ends. This functionality needs
adding in the internal subinterpreters module.

Hi there, I'm running 'EnHackathon' in a couple of weeks, and was wondering if
this could be a good issue for a small team of first-time contributors with
experience in C to work on.
Would anyone be able to offer any guidance for where to start in Modules
Lewis Gaul added the comment:
Hi there, if anyone's able to provide any guidance on this issue I'd be happy
to take a look into it.
Is this a behaviour that is feasible to fix, or should this just be documented
in some way as suggested by Evgeny?

Scanner is not documented in CPython's own re documentation:

say there's no obligation to maintain consistency with public APIs.
Is anyone able to make a call on whether this issue
Lewis Gaul added the comment:
Hi all, I'm a newcomer interested in making this small fix, but it looks like
this has become a bit of a contentious issue. Are there any advances on whether
this is a desirable fix?
