[savannahostrowski]

• Issue: Cannot use lazy translation proxies in argparse help #148468

@hugovk (since it's colour-related) @clytaemnestra Perhaps one or both of you have some cycles to review this one :) ?

[hugovk]

I left a comment at #148468 (comment) that I can no longer repro the MRE with latest 3.15 and main.

Is this change still needed or useful?

[savannahostrowski]

Yes, seems like it. #148468 (comment)

[hugovk]

Thanks!
