Dylan DPC abaa78baeb Rollup merge of #78748 - fanzier:tuple-assignment, r=petrochenkov ... Implement destructuring assignment for tuples This is the first step towards implementing destructuring assignment (RFC: https://github.com/rust-lang/rfcs/pull/2909, tracking issue: #71126). This PR is the first part of #71156, which was split up to allow for easier review. Quick summary: This change allows destructuring the LHS of an assignment if it's a (possibly nested) tuple. It is implemented via a desugaring (AST -> HIR lowering) as follows: ```rust (a,b) = (1,2) ``` ... becomes ... ```rust { let (lhs0,lhs1) = (1,2); a = lhs0; b = lhs1; } ``` Thanks to `@varkor` who helped with the implementation, particularly around default binding modes. r? `@petrochenkov`		2020-11-09 01:13:44 +01:00
