handles :: forall m. Functor m => ((Maybe Handle, Maybe Handle, Maybe Handle) -> m (Maybe Handle, Maybe Handle, Maybe Handle)) -> (Maybe Handle, Maybe Handle, Maybe Handle, ProcessHandle) -> m (Maybe Handle, Maybe Handle, Maybe Handle, ProcessHandle)

nohandles :: forall m. Applicative m => (() -> m ()) -> (Maybe Handle, Maybe Handle, Maybe Handle) -> m (Maybe Handle, Maybe Handle, Maybe Handle)

handlesioe :: forall m. Applicative m => ((Handle, Handle, Handle) -> m (Handle, Handle, Handle)) -> (Maybe Handle, Maybe Handle, Maybe Handle) -> m (Maybe Handle, Maybe Handle, Maybe Handle)

A Prism that removes the Maybes from stdin, stdout and stderr or fails to match if any of them is Nothing.
