Re: Language support for flexible handling of system-detected errors.

I have not programmed MSVC++ in quite some time, so my memory of all the
situations there has faded. (Time heals all wounds. :-) I have not spent any
time considering how one might go about getting similar effects into Ada
with or without comment markers. I suspect that mostly, you're right - you
could probably auto-generate a variety of packages that are auto-withed into
code the programmer has to develop & cover most of the territory. I'm just
suspicious that given the mission of duplicating the programming model and
all of its capabilities, there might be some burrs hanging off the edges
that you'd have a hard time finding a good way of doing without some kind of
kludge.

Of course, one might want to ask the question "why bother duplicating the
MSVC++ model at all?" I could imagine better ways of doing it might be
possible. If you start with a solid base, you can keep polishing and
polishing it for years. But if the base is no good, you're just polishing a
turd.
