If you have void F1(MyType1 x) { // do something } void F1(MyType2 x) { // do something else } and for some reason you need to call the first overload of F1 but with x = null, then doing simply F1(null); will not compile as the call is ambiguous. To counter this you can do F1...

There are a number of different methods that can be used to create the same type of expression. The expressions intro mentioned the :() syntax.
