I currently have a situation where I want to have a function

I thought maybe Nullable!int might work:
void foo(Nullable!int) {}
void main()

foo(1); // error
int x;
foo(x); // error
}
Can somebody enlighten me what this topic is about?
I thought an optional parameter would be as easy as
void foo(int i = 0) { writeln(i); }
void main()
{
int x;
foo(x);
foo(1);
foo();
}
Is the Nullable!int approach because 'i' would always
"optionally" be 0 if not passed with above 'foo'?
