For the record, the solution we've settled on as the "best 
compromise" is an external factory function feeding into a 
(generated) constructor. That *seems* to work, since the mocker 
at least is init/copy-safe, and usually none of the fields need 
to *reference* the other fields. But it's still a workaround that 
should not be necessary.
