C++ is a horrible example of how exceptions should be done, so if
you're basing what you want off of that, then that makes me think that
you should be better familiar with how other, more recent languages
use them (though maybe you're quite familiar with how C# and/or Java
use Exceptions, I don't know). From using Java, I think that how it
handles exceptions in general is _far_ superior to how they're
frequently dealt with in C++ (though that does tend to depend on who's
doing the developing, since you _can_ have a decent exception
hierarchy in C++).

The basic problem with C++ exceptions is that it allows you to throw
literally *anything*.
I agree that that was a design mistake, but it's easy to opt out the
unnecessary part. All C++ applications I've worked with define exception
hierarchies. In fact at Facebook we have a lint rule that prohibits
throwing arbitrary stuff.
