Rollup merge of rust-lang#131549 - compiler-errors:try-in-sync, r=spastorino Add a note for `?` on a `impl Future<Output = Result<..>>` in sync function It's confusing to `?` a future of a result in a sync function. We have a suggestion to `.await` it if we're in an async function, but not a sync function. Note that this is the case for sync functions, at least. Let's be a bit more vague about a fix, since it's somewhat context dependent. For example, you could block on it, or you could make your function asynchronous. 🤷
