ghci ignores -fprint-explicit-runtime-reps
The docs here mentions the following use-case:
ghci> :t ($)
($) :: (a -> b) -> a -> b
ghci> :set -fprint-explicit-runtime-reps
ghci> :t ($)
($)
:: forall (r :: GHC.Types.RuntimeRep) a (b :: TYPE r).
(a -> b) -> a -> b
However, I get this:
GHCi, version 8.0.2: http://www.haskell.org/ghc/ :? for help
Prelude> :t ($)
($) :: (a -> b) -> a -> b
Prelude> :i ($)
($) ::
forall (r :: GHC.Types.RuntimeRep) a (b :: TYPE r).
(a -> b) -> a -> b
-- Defined in ‘GHC.Base’
infixr 0 $
Prelude> :set -fprint-explicit-runtime-reps
Prelude> :t ($)
($) :: (a -> b) -> a -> b
Prelude> :i ($)
($) ::
forall (r :: GHC.Types.RuntimeRep) a (b :: TYPE r).
(a -> b) -> a -> b
-- Defined in ‘GHC.Base’
infixr 0 $
I'm not sure if the docs are wrong or GHCi is erroneously ignoring the flag when using :t
.
