How about a system in which you can say whether an exception is I/O
related, network related, recoverable or not, should be displayed to the
user or not, etc. Such is difficult to represent with inheritance alone.
That may sound great on the paper, but it isn't. The fact that an
exception is recoverable or not depend often on your program and not on
the cause of the exception.
This is self-evident. Again, the meaning of "recoverable" is "operation
may succeed if retried with the same input". It's a hint for the catch
code. Of course the program is free to ignore that aspect, retry a
number of times, log, display user feedback, and so on. But as far as
definition goes the notion is cut and dried.
