What’s the means of the symbol “^.”, “^?” and “.:” ?
I'm newbie in haskell. In module import, many symbol lead me to confuse. Like below:
import Control.Lens (at, has, ix, view, (^.), (^?))
import Data.Aeson (Value, withObject, (.:))
import Turtle hiding (env, has, view, (<>))
I have been tried search by google, but there's no result to display. Can anyone tell me the difference about
