Object-C shows this is doable in a very C-like language, and the Boo language shows that in a statically typed language it can be useful to use a Duck type once in a while to reduce the "static type pressure". More info on this last concept in the Boo site.

It would be nice if this worked with structs as parameters as well:

struct X
{
	int a;
	int b;
}


foo(X x)
{

}

foo(x.a = 10, x.b = 20);
