I agree with you on most points. What I meant is that the idea of being
able to pass a parameter (even if only one) when raising an exception is
much better than Ada's current approach where the only thing you can
pass is a string.

This would have been a very simple change to the language (almost as
simple as including a string parameter in an exception occurence), and
the mechanism can be used to simulate a hierarchy of exceptions, using a
single exception with a tagged type as a paramter.
