Many years ago, when i was involved with an Ada83 tool that
had an X Windows interface, we used C wrappers to call the
Ada routines, and passed pointers to the C wrappers to the
callback engine.
More recently, in an embedded system, we used machine code
to branch to a supplied address, and used 'ADDRESS of the
parameterless procedures to set up the callback routines.
This worked in our particular environment (exceptions even
propagated correctly through the indirect subroutine call),
but we had to insure this on our own, since we were going
well outside the definition of the language.
