[matthiaskrgr]

But with debug assertions (@ 4bb15759d7eb519be70c9a955dba9be09e13c06d), we will trigger

            debug_assert!(!erased.needs_infer(), "{:?}", erased);

Which is terrible because there is no actual ICE text but also more interesting because I don't think I have seen this one before:

[matthiaskrgr]

Ah, I can see that that the code of #95134 also hits the debug assertion 👍
