Changes (by carter):

 * status:  new => closed
 * resolution:   => invalid


Comment:

 ~ is already used by haskell for type equality in constraints, eg  `(size
 ~7 )=> SizedList size Int`
 so its not clear how  adding a new meaning for ~ would improve matters.

 closing this as invalid baring discussion on libraries list, ghc-users,
 ghc-devs or #ghc irc channel to the contrary.
 (that is, some additional discussion should happen on a mailing list for
 this proprosal to have teeth.)
