Comment (by nakaji_dayo):

 Replying to [comment:22 mgsloan]:

 I agree. I think "-Wpartial-fields" is good name.


 I have submitted code review about `-Wpartial-fields`.\\
 On the other hand, I don't have any commit about `-Wpartial-field-usages`.

 > I think it also makes sense to have an option to emit warnings for
 partial record fields. Perhaps call it -Wpartial-field-usages? The reason
 this is helpful is that some libraries may export partial fields. It's
 still helpful as a sanity check for users of a library to have this as an
 optional warning.

 I think that this is helpful in this case too.

 But as far as I know, GHC doesn't have warnings for usage of partial
 function.\\
 In case of implement this, it seems that design considering the whole is
 necessary.\\

 Is my understanding correct?
