[gecode-users] wrapping SetVar

You do not have to use pointers to views, just use the views  
directly. They are themselves just thin wrappers around a pointer to  
the actual variable implementation. Allocating a view on the stack  
costs exactly the same as allocating a pointer variable. If you  
really want to use pointers, you could consider using the pointer  
returned by SetView::variable(void).

This will work!

No, please don't.
