Hello!
Suppose we have functions
f :: ReaderT env monad1 rtype g :: Reader env rtype
and we need to call g from f.
Currently I write something like
f = do env <- ask let r = runReader g env doSmth r
I don't like doing it this way (I need to get environment and explicitly pass it). Is there another way to get things done?
How about:
toReaderT :: (Monad m) => Reader r a -> ReaderT r m a toReaderT (Reader f) = ReaderT (return . f)
Thanks. -- WBR, Max Vasin.
