Are you sure that the above doesn't work?
try { throw my_exception(); } catch(...) { try { call_function_that_throws(); } catch( ... ) { }
throw; // works }
No, I'm not sure, but if some_future.wait() switches to a new fiber I am concerned that it won't, because the exception state is per-thread, not per-fiber.
