We cannot do that for `&Vec` because `#[rustc_on_unimplemented]` is limited (it does not clean generic instantiation for references, only for ADTs).

Fix indices and remove some unwraps in arg mismatch algorithm

This is a more conservative fix than rust-lang#97542, addressing some indices which were used incorectly and unwraps which are bound to panic (e.g. when the provided and expected arg counts differ). Beta nominating this as it's quite easy to cause ICEs -- I wrote a fuzzer and found hundreds of examples of ICEs.

fixes rust-lang#97484
r? `@jackh726` this should be _much_ easier to review than the other PR 😅

Don't suggest adding `let` in certain `if` conditions

Avoid being too eager to suggest `let` in an `if` condition with an `=`, namely when the LHS of the `=` isn't even valid as a pattern (to a first degree approximation).

This heustic I came up with kinda sucks. Let me know if it needs to be refined.

Suggest escaping `box` as identifier

Fixes rust-lang#97810.

…emented, r=compiler-errors

Suggest using `iter()` or `into_iter()` for `Vec`

We cannot do that for `&Vec` because `#[rustc_on_unimplemented]` is limited (it does not clean generic instantiation for references, only for ADTs).
