Description

Choose one: is this a bug report or feature request? Feature request

@GeoffreyBooth I came across an unsupported export syntax that appears to be standard

Input Code

export {foo, bar} = item

Expected Behavior

Should transpile to export var {foo, bar} = item

Context

Not blocking anything, just came across it while working on AST stuff

Environment

  • CoffeeScript version:
  • Node.js version:

Contributor guide

Research direction
