A simpler case example:

struct Foo(T) {
    Node!T head;
    struct Node(T) {}
}
void main() {
    Foo!int f;
}


dmd 2.043 prints many errors:

test.d(2): Error: template instance Node!(int) forward references template
declaration Node(T)

test.d(2): Error: Node!(int) is used as a type
test.d(2): Error: variable test.Foo!(int).Foo.head voids have no value
test.d(6): Error: template instance test.Foo!(int) error instantiating
