The issue here isn't deep vs. flat hierarchy (like the rest of the thread),
it's about improving code clarity/dry.
This is much like the 'case A, B:' syntax (or fallthrough/goto case) in
switches.
Even with a flat hierarchy, you might still want to handle a set of
exceptions deriving from Exce

The call is rewriten to _aa_len(aa) and checks for null.
This can almost be done with a normal class, except the compiler inserts a
null check into each member function, iirc.
I guess that's another bit of magic that can't be handled simply.
It can still be done with a struct:

Well, since keys would be string, you can define them at the base
class.
So, FileException can define a few detail names that you know are
used in its derived classes. And so, Exception can define detail
names that are standard for all classes.
So it would look like:
class FileException {

Thanks for an insightful post. If you found the time, it would be great
if you could translate your paper on exceptions from Spanish.

To me, this is a giant hint that OOP is a good solution. You want a
class hierarchy rooted at Exception. And groups of related exceptions
probably should be rooted under their respective base classes under
Exception.
