	  The result is the map element value indexed by the key.
	  Key invocations may be chained and combined with fields to any
	  depth:
	    .Field1.Key1.Field2.Key2
	  Although the key must be an alphanumeric identifier, unlike with
	  field names they do not need to start with an upper case letter.
	  Keys can also be evaluated on variables, including chaining:
	    $x.key1.key2
