Ok, it has to be said again: exceptions need to be first class objects.

Changing an exception into another is trivial in most languages, typically by
wrapping it with another of the desired kind.

Ada's difficulties with manipulating exceptions are completely self induced.

Real languages don't have a trash can. There is a janitor in the background
cleaning everything up. Exceptions are the only thing left to throw >-).

Ada is a pretty good language. Garbage collection is a step up the
evolutionary ladder though, and needs to be available within Ada as well,
perhaps under programmer control to be disabled when necessary.  Google some
previous threads for my arguments on this topic.
