Hmm, thanks for doing this, but ...

... why all the new *.dump files? That's far more code churn than was
necessary, as the original *.d files served their purpose quite fine,
while the new tests would only have needed to reference those *.d ones.
Anyway - I guess it is as it is now, but please consider (prefer) the
alternative in the future.
