Improve E0308 error message wording again Hello again, I recently did this PR: #70242 I felt the error message could be further improved, so I made [a post on the Rust community forum](https://users.rust-lang.org/t/looking-for-feedback-on-an-improved-error-message-for-e0308/40004) to ask for feedback. (Also, there were some comments on my original PR that I took into consideration as well.) This PR is my attempt to take all the feedback into account and propose a better and simplified error message that should still be accurate. Its main benefit is having simpler grammar, and hopefully being easier to read and understand. Thanks to everyone who commented and gave feedback, and thank you for taking a look at this PR.

2020-04-22Rollup merge of #70998 - estebank:suggest-impl-trait-empty-fn, r=varkorYuki Okushi-2/+1
Suggest `-> impl Trait` and `-> Box<dyn Trait>` on fn that doesn't return During development, a function could have a return type set that is a bare trait object by accident. We already suggest using either a boxed trait object or `impl Trait` if the return paths will allow it. We now do so too when there are *no* return paths or they all resolve to `!`. We still don't handle cases where the trait object is *not* the entirety of the return type gracefully. Closes #38376.

2020-04-20Ensure tail expression will have a `Ty` for E0746Esteban Küber-2/+1
When the return type is `!Sized` we look for all the returned expressions in the body to fetch their types and provide a reasonable suggestion. The tail expression of the body is normally evaluated after checking whether the return type is `Sized`. Changing the order of the evaluation produces undesirable knock down effects, so we detect the specific case that newcomers are likely to encounter ,returning a single bare trait object, and only in that case we evaluate the tail expression's type so that the suggestion will be accurate.

2020-04-09Rollup merge of #70916 - Centril:track-caller-ffi, r=eddybMazdak Farrokhzad-12/+1
Support `#[track_caller]` on functions in `extern "Rust" { ... }` Fixes https://github.com/rust-lang/rust/issues/70830 which is the follow-up to @eddyb's suggestion in https://github.com/rust-lang/rust/pull/69251#discussion_r380791634 to allow `#[track_caller]` on `fn`s in FFI imports, that is, on functions in `extern "Rust" { ... }` blocks. This requires that the other side, the FFI export, also have the `#[track_caller]` attribute. Otherwise, undefined behavior is triggered and the blame lies, as usual, with the `unsafe { ... }` block which called the FFI imported function. After this PR, all forms of `fn` items with the right ABI (`"Rust"`) support `#[track_caller]`. As a drive-by, the PR also hardens the check rejecting `#[naked] #[track_caller]` such that methods and other forms of `fn` items are also considered. r? @eddyb cc @rust-lang/lang
