------------------------------------------+---------------------------------
 Requesting second parameter of scoped_ptr (and other smart pointers)
 templates, specifying destroy operation for pointer. Something like this
 (simplified code):

 {{{
 template <class T>
 struct destroy_delete {
   static void destroy(T* t) { delete t; }
 };

 template <class T, class D = destroy_delete>
 class scoped_ptr {
   ~scoped_ptr() {
     D::destroy(px);
   }
 };


 // this I can use in my code
 template <class T>
 struct destroy_free {
   static void destroy(T* t) { free(t); }
 };

 }}}
