In trying to understand
 [http://www.haskell.org/ghc/docs/latest/html/users_guide/pragmas.html the
 documentation on pragmas] I could not figure out where to place a pragma
 of the form:
 {{{ {-# DEPRECATED f, C, T "Don't use these" #-} }}}

 for instance, in Distribution.Setup.hs, I tried to add:
 {{{
 {-# DEPRECATED CopyPrefix "Don't use this." #-}

 data CopyDest
   = NoCopyDest
   | CopyTo FilePath
   | CopyPrefix FilePath         -- DEPRECATED
   deriving (Eq, Show)
 }}}

 but got the error:
 {{{
 ./Distribution/Setup.hs:172:15:
     Not in scope: type constructor or class `CopyPrefix'
 }}}
