"This package contains the @code{Control.Monad.Fail} module providing the

class that became available in
@uref{https://hackage.haskell.org/package/base-4.9.0.0, base-4.9.0.0} for
older @code{base} package versions. This package turns into an empty package
when used with GHC versions which already provide the
@code{Control.Monad.Fail} module.")
