Ada may not allow passing functions as parameters, but you can either
instantiate a generic procedure and call that, or do without the notion
of call-back procedures at the Ada level and do it in a different style,
either by posting back events or by actual rendez-vous...

As far as "extending Ada" goes, whoever proposed that one must have forgotten
