Description

Goal

Allow users to use destructuring assignment.

Overview

Destructuring assignment is pretty helpful and should be implemented. Destructured variables should become locals. Destructured variables should not need type annotation as they can be inferred, so that is super useful.

Acceptance Criteria

  • const [x, y] = arrayObject;
  • const {x, y} = vectorObject;
  • Type annotations for destructured locals are not necessary
  • Tests

Research direction
The issue requests implementing destructuring assignment in the Walt language. Start by examining the existing parser and AST structure in the src/ directory, particularly files related to syntax parsing and code generation. Review the acceptance criteria for array and object destructuring. There are no linked pull requests; the issue has been open since 2018 with minimal discussion, so understanding the current compiler architecture is key. Maintainers may have additional context in comments (if any) or in the repository's documentation.
