Record wildcard

| Just to clarify, does ghc still accept the traditional record puns (in

| augments puns to include wildcards?  Or are wildcarded-puns the only
| kind that ghc now accepts?

Good qn.  At the moment GHC does not accept
        f (C {f,g,h}) = ...
but it's arguably a useful half-way house between
        f (C {f=f,g=g,h=h}) = ...
and
        f (C {..}) = ...
