bors 1af55d19c7 Auto merge of #89933 - est31:let_else, r=michaelwoerister ... Adopt let_else across the compiler This performs a substitution of code following the pattern: ``` let <id> = if let <pat> = ... { identity } else { ... : ! }; ``` To simplify it to: ``` let <pat> = ... { identity } else { ... : ! }; ``` By adopting the `let_else` feature (cc #87335). The PR also updates the syn crate because the currently used version of the crate doesn't support `let_else` syntax yet. Note: Generally I'm the person who *removes* usages of unstable features from the compiler, not adds more usages of them, but in this instance I think it hopefully helps the feature get stabilized sooner and in a better state. I have written a [comment](https://github.com/rust-lang/rust/issues/87335#issuecomment-944846205) on the tracking issue about my experience and what I feel could be improved before stabilization of `let_else`.		2021-10-19 14:41:39 +00:00
