Perhaps. However, the general intent was to produce the lightest, most
efficient objects possible. If the only data in an exception is a vtable
pointer, then the exception object will typically be half the size of
one that gratuitously includes an int as well. It's a trivial task to
add an int to a derived type - impossible to remove one.
Or did you mean that a virtual which()/why() method would have been
useful?
