<<>:~ ) :: Semigroup m => LensLike ((,) m) s t m m -> m -> s -> (m, t)lens Control.Lens.Lens (<>) a Semigroup value onto the front of the target of a Lens and return the result. However, unlike (<<>~), it is prepended to the head side. When you do not need the result of the operation, (<>:~) is more flexible.

However, unlike (<<<>=), it is prepended to the head side. When you do not need the result of the operation, (<>:=) is more flexible.

(
.: ) :: FromJSON a => Object -> Key -> Parser agogol-core Gogol.Data.JSON Retrieve the value associated with the given key of an Object. The result is empty if the key is not present or the value cannot be converted to the desired type. This accessor is appropriate if the key and value must be present in an object for it to be valid. If the key and value are optional, use .:? instead.
