Replying to [comment:19 RyanGlScott]:
> We could include this warning under the scope of -Wincomplete-patterns,
but I think it's best to keep these two things separate, since one might
conceivably wish to disable partial record warnings while still having
-Wincomplete-patterns on.
I agree. I thought it is safety to separate it.
> Yes. The underscore prefix is already an established convention for
silencing other warnings.
Thanks a lot. I learned.\\
I agree. This rule seems even good in `partial record selector` case.
