Just use the Win32 API way when STRICT is defined:

---
  struct HANDLE__{ int unused; }
  alias HANDLE__* HANDLE;
---

for different handles, just create a template that creates 
different handles with different names:

---
  mixin DEFINE_HANDLE("HWND");

  // struct HWND__{ int unused; }
  // alias HWND__* HWND;
---
