Add -fshow-runtime-rep
As discussed in several interwoven threads (original, café), it has been suggested to add a flag -fshow-runtime-rep. Without this flag enabled, the pretty printer will instantiate any RuntimeRep type parameters to PtrRep Lifted. This has the effect of changing
($) :: forall (r :: RuntimeRep) (a :: *) (b :: TYPE r). (a -> b) -> a -> bto
($) :: (a -> b) -> a -> bunder the default GHCi settings.
Note that Levity becomes RuntimeRep after #11471 (closed) is complete.
