Disable the struct's default constructor, which implicitly 
disables struct literals for it [1].

---
struct A
{
     int a;
     string b;
     @disable this(); // Disable the default constructor -> 
implicitly disables struct literals
}
---

Structs have only a single default constructors (with zero 
arguments) - which you can disable (as shown above); you were 
using struct literals [2].

If I understand you correctly, that is what you get when you 
@disable the default constructor (again, there is only the zero 
arguments one).
You will have to initialize your structs, explicitly, then, 
though, i.e. `A a = A.init`.
