@WG-prioritization/alerts issue #80207 has been requested for prioritization.
I feel quite confused by this one; why did the code used to compile even though the return type was unsized? It seems like the code shouldn't compile, though it definitely shouldn't be ICEing.
Anyway, maybe P-high.
The code used to compile because of the
Self: Sized bound
so it was "just" uncallable as
dyn Trait is never sized
consider that you were actually unable to use that impl
P-high seems fine to me even though it is a regression
Ah, I see: the impl wouldn't cause an error, but any call to the method would.
Issue #80207's prioritization request has been removed.
