    if (value instanceof Text) {
      const string = value.stringValue();
      if (string === "true") {
        return Bool.from(true);
      } else if (string === "false") {
        return Bool.from(false);
      }
    }

  }

ident(value: Value): Value {
    if (value instanceof Text) {
      const string = value.stringValue();
      if (string === "true") {

      } else if (string === "false") {
        return Bool.from(false);
      }
