Right, I fully agree. Ada is overloaded with "special" features.
I prefer exceptions become a "normal" discrete type (only in the interface
of). I wished to have ranges of exceptions so that one could define a group
of related exceptions, and be able to extend such groups. This could the
first step in order to make exceptions contracted.
There is a similar important case, the type tags. Tags and exceptions have
much in common. It would be very nice to find a generic mechanism for
handling such things. That would remove a lot of "magic" from the language,
IMO.
