☔ The latest upstream changes (presumably #66175) made this pull request unmergeable. Please resolve the merge conflicts.

[Mark-Simulacrum]

Rebased. Somehow on_unimplemented de-stabilized? Not sure.

@Centril I can't seem to get on_unimplemented working -- if I remove it, then I get:

but if I leave it in, then I get:

[Centril]

@Mark-Simulacrum Odd; What I did in #65794 was to move the attribute under #![feature(rustc_attrs)].

[Mark-Simulacrum]

libstd does have the rustc_attrs attribute. I wonder if maybe I should keep the cfg(bootstrap) around...

[Centril]

Sure, if that makes things compile, why not. We can remove it next time. :)

[Mark-Simulacrum]

@pietroalbini Okay, looks like this is compiling successfully now.
