Comment (by simonpj):

 Totally agree.

 But it's not entirely straightforward

  * The other branches might be highly relevant.  Eg
 {{{
 f x = case x of
         True -> False
         False -> 'x'
 }}}

  * The printing machinery doesn't (currently) know or take account of
 where the original focus point was.  Making it do so would be possible,
 but would take real work.

 I'd be happy if someone wanted to develop ideas here.

 Simon
