I'm not sure that is quite right -- the point of raising the exception
on move is to "back out" of any further work at that point, and up
through several layers of call stack.  If we move to an event, then we
have to revisit all those layers, to ensure that the "termination path"
does no work after the event is emitted.

Likewise, we run the risk of breaking third-party code which already
expects to raise the exception.
