usingPairs

Add JSON name/value pairs. Typically used with a forEach call, for example:

		members.add(Event::getLabels).usingPairs(Map::forEach);

When used with a named member, the pairs will be added as a new JSON value object:

		{
		  "name": {
		    "p1": 1,
		    "p2": 2
		  }
		}

When used with an unnamed member the pairs will be added to the existing JSON object:

		{
		  "p1": 1,
		  "p2": 2
		}
