Hey

I've got my new const callback class for transactions:

   template<class T, typename Arg1, typename Arg2>
   class Callback_0Data_2Arg_const : public CallbackBase_0Data {
   public:
Callback_0Data_2Arg_const(T* ptr, void (T::*pmf)(Arg1, Arg2) const, Arg1 arg1, Arg2 arg2)
       : ptr(ptr), pmf(pmf), arg1(arg1), arg2(arg2)
   {
   }
       virtual ~Callback_0Data_2Arg_const()
   {
   }
       virtual void call()
   {
           (ptr->*pmf)(arg1, arg2);
   }
   private:
       T* ptr;
       void (T::*pmf)(Arg1, Arg2) const;
       Arg1 arg1;
       Arg2 arg2;
   };

And my create function:

   template<class T, typename Arg1, typename Arg2> static
   CallbackBase_0Data*
   create(T* ptr, void (T::*pmf)(Arg1, Arg2) const, Arg1 arg1, Arg2 arg2) {
return new Callback_0Data_2Arg_const<T, Arg1, Arg2>(ptr, pmf, arg1, arg2);
   }

Now I want to create a callback for the method:

FMantaWindow::addCuttingPlane( Point &point, Vector &normal );


Problem is that Arg1 and Arg2 in create don't take references. So the create function doesn't match. (At least I think that's why, but even though this part of manta's code is template nirvana, it makes my head spin. ;-) ) Anyone see a reason not to make Arg1 and Arg2 of create's formal arguments references? (I'm about 65% sure I know what change would do, but maybe someone else can parse this and tell me if it sounds good....)
