runReaderTNat :: r -> ReaderT r m :~> m Source #
logWriterTSNat :: MonadIO m => (w -> IO ()) -> WriterT w m :~> m Source #
Log the contents of WriterT with the function provided as the
first argument, and return the value of the WriterT computation
logWriterTLNat :: MonadIO m => (w -> IO ()) -> WriterT w m :~> m Source #
Like logWriterTSNat, but for lazy WriterT.
generalizeNat :: Applicative m => Identity :~> m Source #
Like mmorph's generalize.
