Enum values should be objects

[marcoscaceres]

Given:

enum Things {
    "foo",
    "bar"
};

Enum values current result in,

[
  {
    "type": "ws",
    "value": "\n          "
  },
  "foo",
  {
    "type": ","
  },
  {
    "type": "ws",
    "value": "\n          "
  },
  "bar",
  {
    "type": "ws",
    "value": "\n        "
  }
]

This switching of types makes things really inconsistent. Would have expected an Object like:

  {
    "type": "enum-value",
    "value": "foo",
  }

And maybe, for compat:

  {
    "type": "enum-value",
    "value": "foo",
    toString(){
       return this.value;
    }
  }
