Everybody is claiming that using lift is a bad thing.
So, I come to remedy this problem.
Stop lifting, start using shinny operators like this one:
(^$) :: Monad m => m a -> (a -> b -> c) -> m b -> m c
(^$) = flip liftM2
Then you can do wonderful stuff and you will never read the four-letter
word in your code again:
\> Just 42 ^$(+)$ Nothing
Nothing
\> Just 10 ^$(+)$ Just 20
Just 30
\> let add = (+)
\> Just 30 ^$ add $ Just 12
Just 42
