Run with deno test.

Correct AST should be same as for { a: a = b } where both a's are the same node:

{
  "type": "ObjectPattern",
  "properties": [
    {
      "type": "Property",
      "key": {
        "type": "Identifier",
        "name": "a",
      },
      "kind": "init",
      "shorthand": true,
      "value": {
        "type": "AssignmentPattern",
        "left": {
          "type": "Identifier",
          "name": "a",
        },
        "optional": false,
        "right": {
          "type": "Identifier",
          "name": "b",
        }
      }
    }
  ]
}
