Comment:

 Another example of this logic leading the user into a direction that will
 cause a different error:

 {{{
 Prelude> let foo = ()
 Prelude> let g = Foo  -- good suggestion

 <interactive>:5:9:
     Not in scope: data constructor ‘Foo’
     Perhaps you meant variable ‘foo’ (line 2)
 Prelude> let f (Foo x) = x  -- bad suggestion

 <interactive>:3:8:
     Not in scope: data constructor ‘Foo’
     Perhaps you meant variable ‘foo’ (line 2)
 }}}

 Anyways, I pushed it to `wip/T9177` for review (but will likely push to
 master in the next days; people can still complain afterwards).
