        Object key = array.length == 0 ? null : array[0];
        Object value = array.length <= 1 ? null : array[1];
        leftShift(result, new MapEntry(key, value));
    } else {
        // TODO: enforce stricter behavior?
        // given Map.Entry is an interface, we get a proxy which gives us lots
        // of flexibility but sometimes the error messages might be unexpected
        leftShift(result, asType(newEntry, Map.Entry.class));
    }
