It depends on how you look at it. In D a delegate is a function pointer 
with a context pointer. In C++ a pointer to a member function is 
basically the same, the context pointer is just passed separately.

To do what? As far as I know C++ doesn't have anything corresponding to 
a D delegate.

Actually I don't see why you can't use a delegate for this. The only 
difference is that it won't be virtual.
