Need size of rightmost array, not type...

[Ary Manzana]

This compiles fine:

----------------------------------------
template Foo() {
	const int Foo = 3;
}

void one() {
	int x = Foo!();
	char[] buf = new char[x];
}
----------------------------------------

However this:

----------------------------------------
template Foo() {
	const int Foo = 3;
}

void two() {
	char[] buf = new char[Foo!()];
}
----------------------------------------

main.d(6): need size of rightmost array, not type Foo!()

Why?
