Groovy Goodness: Tuples With Up To 9 Items

A tuple is an ordered, immutable list of elements. Groovy supported tuples with one or two elements before Groovy 2.5.0. Since Groovy 2.5.0 we can use tuples with maximal nine items. Groovy added the classes Tuple3 up to Tuple9. The bonus we get compared to an unmodifiable list with elements is that we can use properties like first, second, third, fourth, fifth, sixth, seventh, eighth, ninth to get items at the specified position.

In the following example we use different Tuple classes:
