  1. liftA2 :: Applicative f => (a -> b -> c) -> f a -> f b -> f c

    dimensional Numeric.Units.Dimensional.Prelude

    Lift a binary function to actions. Some functors support an implementation of liftA2 that is more efficient than the default one. In particular, if fmap is an expensive operation, it is likely better to use liftA2 than to fmap over the structure and then use <*>. This became a typeclass method in 4.10.0.0. Prior to that, it was a function defined in terms of <*> and fmap.

    Example

    >>> liftA2 (,) (Just 3) (Just 5)
Just (3,5)

    >>> liftA2 (+) [1, 2, 3] [4, 5, 6]
[5,6,7,6,7,8,7,8,9]
