You'll need a new feature name with the version CURRENT_RUSTC_VERSION in since.

@thaliaarchi i think i got it 🤞 , bear with me if i made a newbie mistake

Well it looks good to me! I’m not in a Rust team, so my approval doesn’t mean anything, but you should hear back from someone within two weeks.

The return of the GroupBy and GroupByMut iterators on slice #79895 (initial PR)

No mention of Clone as far as I can see, so perhaps this was just an oversight?
