           Summary: cxtern(C++) array parameter mangling gains surprise
                    const
           Product: D

extern(C++) void f(int[4]* t);
Mangles as: void __cdecl f(int (* const)[4])

Where did that const come from?

This would logically be connected to a C++ function declared:
  void f(int(*x)[4]);
Which mangles: void __cdecl f(int (*)[4])

I think it very unlikely that any C++ user would have functions:
  void f(int(*const x)[4]);

Nobody uses *const in C++.
