You can declare an array whose the element type matches to one of 
the template parameter:

---
struct Foo(T)
{
     Foo!T[] foos;
     // typeof(this)[] foos // equivalent
}
---

since it's an array (fixed size whatever is the element type: 
size_t len + size_t pointer) it doesn't matter if the template 
declaration is partial.
