Make TAIT behave exactly like RPIT fixes https://github.com/rust-lang/rust/issues/96552 This makes type-alias-impl-trait behave like return-position-impl-trait. Unfortunately it also causes some cases to stop compiling due to "needing type annotations" and makes panicking cause fallback for the hidden type to `()`. All of these are addressable, but we should probably address them for RPIT and TAIT together r? ``@lcnr`` |
