[Haskell-cafe] Missing `$` like operators in Haskell

Below are the `$` like operators in Haskell (view in fixed width): --------------------------------------------------------------------- | Function first | Op | Function second | Op | ------------------------------------------------------------------------------- | Plain | (a -> b) -> a -> b | $ | a -> (a -> b) -> b | | | Functor | (a -> b) -> f a -> f b | <$> | f a -> (a -> b) -> f b | | | Applicat| f (a -> b) -> f a -> f b | <*> | f a -> f (a -> b) -> f b | <**> | | Monad | (a -> m b) -> m a -> m b | =<< | m a -> (a -> m b) -> m b |

...

The "function second" forms I couldn't find for "plain" and "functor". What are the most common operators to used in these places?
