I should also have mentioned that when you declare the primitive
operations of the type to take access parameters, this effectively hides
the fact that you manipulating a pointer. The syntax of method
invokation is the same as for a non-pointer.

The ACM patterns archives also has lots of examples of the access
parameter technique.
