Comment (by simonpj):

 Thanks.  But shouldn't there be some carefully-written text (along the
 lines of my email) in the overlapping-instances section of the manual?

 And likewise, the comments in `Note [Incoherent Instances]` currently
 cover only the narrow question of your email, not the broader issue of my
 original post.  Could you combine the two.  (Also the Note needs a cross-
 ref from `BasicTypes`.)

 Ta

 Simon
