Define "createXXX" functions for the constructors of class XXX

[Johan Engelen via Digitalmars-d-learn]

Hi all,
   While trying to interface C++ and D, I have to new a few D 
objects in C++ code. I am doing this using a D function: "XXX 
createXXX(...) { return new XXX(...); }".
I am sure there must be some great way to automatically generate 
these creator functions, but I don't know how to do it.

In the C++-header I will write manually:
   XXX* createXXX(int a, int b);
   XXX* createXXX(bool flag);

In D source:
   extern (C++) class XXX {
     this(int a, int b) { /+...+/ }
     this(bool flag) { /+...+/ }
   }

// Somehow define these guys automatically, 
"genCreateCtors!(XXX)" ?
   XXX createXXX(int a, int b) { return new XXX(a, b); }
   XXX createXXX(bool flag) { return new XXX(flag); }

Thanks a lot!
   Johan
