..: ) :: FromJSON b => Setter' a b -> Text -> Object -> Parser (a -> a)configuration-tools Configuration.Utils.ConfigFile A variant of the setProperty that uses the default parseJSON method from the FromJSON instance to parse the value of the property. Its usage pattern mimics the usage pattern of the .: operator from the aeson library.

(f ... g) x y === f (g x y)
(
.> ) :: (a -> b) -> (b -> c) -> a -> cflow Flow Left-associative compose operator. Read as "compose forward" or "and then". Use this to create long chains of computation that suggest which direction things move in.

Or use it anywhere you would use (>>>).\ x -> (f .> g) x == g (f x)
\ x -> (f .> g .> h) x == h (g (f x))
