[compiler-errors]

This is (also) #119820, cc @lcnr (though we probably already have this listed as a regression in that one)

[apiraino]

By reading this comment in #119820 I infer that we accepted that change but we wanted to fix all crates regressions before the release.

I'll tentatively assign a P-high (if my understanding is correct).

WG-prioritization assigning priority (Zulip discussion).

@rustbot label -I-prioritize +P-high

but we wanted to fix all crates regressions before the release.

This crate was indeed already fixed in lycantropos/rene#5, and this released crates.io version doesn't contain the fix.
