Empty Tuple

All EmptyTuples are identical.

main() {
  var emptyTuple = EmptyTuple();
  assert(emptyTuple == EmptyTuple());
}

One-Tuple

main() {
  var oneTupleWithString = Tuple1<String>('hello world!');
  var oneTupleWithInt = Tuple1<int>(1);
  print("One tuple contains ${oneTupleWithInt.item0}");
}

Two-Tuple

main() {
  var twoTupleWithSameTypes = Tuple2<int, int>(1, 2);
  var twoTupleWithDifferentTypes = Tuple2<int, String>(1, 'X');
  print("Two tuple contains ${twoTupleWithSameTypes.item0}, "
  " and ${twoTupleWithSameTypes.item1}");
}
