Actually Alfred, Ada 95 *does* support the equivalent of C function
pointers, although you'll have to use the Ada terminology "access to
subprogram" to find them.
If you really want to be a trouble-maker, you'll complain that the
limitations on them make them only as powerful as C's function pointers,
and less powerful than Pascal's function arguments (terminology?), and in
that case I can point you directly to the long arguments on why they are
so restricted :-)
