I tested it and found that the reverse operation of the reserved word 'new'
is given by the generic package Unchecked_Deallocation in RM-13.11.2.

Instantiating a Free procedure as given in RM-13.11.2(5) works and provides
the required function.

Instead the longish discussions about accessibility rules lead me to the
belief, that access types are like smart pointers.
