Can you offer a real world use-case where the above isn't
sufficient?
What happened is that a file wasn't found. What one wants to
catch is
a FileNotFoundException.
Do you suggest that I have to:
try {
...
} catch (FileNotFoundException ex) {
...
} catch (WithErrorCode!FileNotFoundException ex) {
...
} catch (WithRainbows!FileNotFoundException ex) {
...
}
and so on?

FileNotFoundException is the super class of the others so the
first catch clause is enough. in fact, the others will never be
called if listed in the above order.
