* Do not emit unnecessary E0308 after E0070 * Show fewer errors on `while let` missing `let` * Hide redundant E0308 on `while let` missing `let` * Point at binding definition when possible on invalid assignment * do not point at closure twice * do not suggest `if let` for literals in lhs * account for parameter types
It was replaced several years ago by the stable option `-C overflow-checks`. The goal was to delete the `-Z` flag once users had migrated [1]. Now that it's been several years, it makes sense to delete the old flag. See also the discussion on Zulip [2].

…-obk Diagnostic tweaks * On type mismatch caused by assignment, point at the source of the expectation * Hide redundant errors * Suggest `while let` when `let` is missing in some cases
Various fixes for const_trait_impl A few problems I found while making `Iterator` easier to const-implement. 1. More generous `~const Drop` check. We check for nested fields with caller bounds. For example, an ADT type with fields of types `A`, `B`, `C`, check if all of them are either: - Bounded (`A: ~const Drop`, `B: Copy`) - Known to be able to destruct at compile time (`C = i32`, `struct C(i32)`, `C = some_fn`) 2. Don't treat trait functions marked with `#[default_method_body_is_const]` as stable const fns when checking `const_for` and `const_try` feature gates. I think anyone can review this, so no r? this time.
…ait, r=estebank Print associated types on opaque `impl Trait` types This PR generalizes rust-lang#91021, printing associated types for all opaque `impl Trait` types instead of just special-casing for future. before: ``` error[E0271]: type mismatch resolving `<impl Iterator as Iterator>::Item == u32` ``` after: ``` error[E0271]: type mismatch resolving `<impl Iterator<Item = usize> as Iterator>::Item == u32` ``` --- Questions: 1. I'm kinda lost in binders hell with this one. Is all of the `rebind`ing necessary? 2. Is there a map collection type that will give me a stable iteration order? Doesn't seem like TraitRef is Ord, so I can't just sort later.. 3. I removed the logic that suppresses printing generator projection types. It creates outputs like this [gist](https://gist.github.com/compiler-errors/d6f12fb30079feb1ad1d5f1ab39a3a8d). Should I put that back? 4. I also added spaces between traits, `impl A+B` -> `impl A + B`. I quite like this change, but is there a good reason to keep it like that? r? ```@estebank```
