Revert let_chains stabilization

2022-08-15T07:05:24+00:00

This reverts commit 326646074940222d602f3683d0559088690830f4. It was discovered that they are not implemented correctly, which does not make them ready for stabilization.

Use expr parse restrictions for let expr parsing

dont call type ascription 'cast'

Rollup merge of #98705 - WaffleLapkin:closure_binder, r=cjgillot

Implement `for<>` lifetime binder for closures This PR implements RFC 3216 ([TI](https://github.com/rust-lang/rust/issues/97362)) and allows code like the following: ```rust let _f = for<'a, 'b> |a: &'a A, b: &'b B| -> &'b C { b.c(a) }; // ^^^^^^^^^^^--- new! ``` cc ``@Aaron1011`` ``@cjgillot``

Rollup merge of #99030 - rust-lang:notriddle/field-recovery, r=petrochenkov

2022-07-13T14:02:35+00:00

diagnostics: error messages when struct literals fail to parse If an expression is supplied where a field is expected, the parser can become convinced that it's a shorthand field syntax when it's not. This PR addresses it by explicitly recording the permitted `:` token immediately after the identifier, and also adds a suggestion to insert the name of the field if it looks like a complex expression. Fixes #98917

Parse closure binders

2022-07-12T12:25:16+00:00

This is first step in implementing RFC 3216. - Parse `for<'a>` before closures in ast - Error in lowering - Add `closure_lifetime_binder` feature

Fix last let_chains blocker
