Useful situations for unnamed parameters:
* Declaring a delegate type
void delegate (int) dg;
* Declaring a function/method without implementation
void foo (int);
* Overriding/implementing a method where a parameter isn't needed
class Foo {
abstract void foo (int a);
}
class Bar : Foo {
void foo (int) {}
}
These are the situations I see it as might being useful but I would say that
adding names to the parameters adds documentation and that's always a good
thing.
