Issue Details

---

E.g. add test: await EvaluateOnCallFrame(id, "f[o]" ); to EvaluateObjectByNonIntLocals where object o = 'c'; and f has a property: public object this[object key] => key;. And some more, for a few other object scheme (valuetype and array as well, if it won't make this PR too big).

The result:

  "result": {
    "type": "string",
    "value": "res_c",
    "description": "res_c",
    "objectId": "dotnet:object:"
  }

Reason:
we are keeping indexes in a form of strings. They cannot keep all the information about the indexer if it's an object. We need to start supporting more complex entities.
