The integer type tracking borrow count has a typedef called `BorrowFlag`. This type should be used instead of explicit `isize`.
Usage of `Pin::new_unchecked(&mut …)` is dangerous with `poll_fn`, even though the `!Unpin`-infectiousness has made things smoother. Nonetheless, there are easy ways to avoid the need for any `unsafe` altogether, be it through `Box::pin`ning, or the `pin!` macro. Since the latter only works within an `async` context, showing an example artifically introducing one ought to help people navigate this subtlety with safety and confidence.

…e_impl, r=cjgillot Simplify `Span::source_callee` impl Imo the iterator impl is easier to grasp.
Use BorrowFlag instead of explicit isize The integer type tracking borrow count has a typedef called `BorrowFlag`. This type should be used instead of explicit `isize`.
…ve1, r=WaffleLapkin Rewrite various resolve/diagnostics errors as translatable diagnostics additional question: For trivial strings is it ever accepted to use `fluent_generated::foo` in a `label` for example? Or is an empty struct `Diagnostic` preferred?
…e, r=oli-obk Continue folding in query normalizer on weak aliases Fixes rust-lang#112752 Fixes rust-lang#112731 (same root cause, so didn't make a test for it) fixes rust-lang#112776 r? ```@oli-obk```
Treat TAIT equation as always ambiguous in coherence Not sure why we weren't treating all TAIT equality as ambiguous -- this behavior combined with `DefineOpaqueTypes::No` leads to coherence overlap failures, since we incorrectly consider impls as not overlapping because the obligation `T: From<Foo>` doesn't hold. Fixes rust-lang#112765
…ce, r=fee1-dead
Don't ICE on bound var in `reject_fn_ptr_impls`
We may try to use an impl like `impl<T: FnPtr> PartialEq {}` to satisfy a predicate like `for<T> T: PartialEq` -- don't ICE in that case.
Fixes rust-lang#112735
