Comment (by gridaphobe):

 Actually, including the type signature doesn't seem feasible (or at least
 useful), given that
 {{{
 foo :: Int -> Int
 bar :: Int -> Int

 foo = ...
 bar = ...
 }}}
 is perfectly valid. So let me amend my example [comment:2 above] to
 {{{
 loc = nameLoc 'A.head
   -- loc == A.hs:4:1-5:15
 }}}
