I think the trick is setting up the stack frame in such a way
that the C++ exception mechanism knows there's a catch block
available at all. From there, we should be able to use the
standard interface-to-class method to call virtual functions
on the exception object, and hopefully the C++ runtime will
handle cleanup for us.
What exception object?
throw "bad things happened";
Shouldn't matter. It's just a callback taking a different
parameter type. Though I think it would be a fair limitation to
say that D will only catch objects.
