    The comment in GHC.Base claimed that ($) couldn't be used in that module
    as it was wired-in. However, this is no longer true; ($) is merely known
    key and is defined in Haskell (with a RuntimeRep-polymorphic type) in
    GHC.Base.
    
    The one piece of magic that ($) retains is that it a special typing
    rule to allow type inference with higher-rank types
    (e.g. `runST $ blah`; see Note [Typing rule for ($)] in TcExpr).
