1. (^:) :: T r a -> (a -> a) -> r -> r

   data-accessor	Data.Accessor

   modify as infix operator. This lets us write field^:subfield^:(2*) $ record, record$%field^:subfield^:(2*) or record$%field^:subfield^:(const 1).

2. (^:) :: T r a -> (a -> a) -> r -> r

   data-accessor	Data.Accessor.Basic

   modify as infix operator. This lets us write field^:subfield^:(2*) $ record, record$%field^:subfield^:(2*) or record$%field^:subfield^:(const 1).

3. (%:) :: forall (m :: Type -> Type) r a . Monad m => T r a -> (a -> a) -> StateT r m ()

   data-accessor	Data.Accessor.MonadState

   Infix variant of modify.

4. (?:) :: Maybe a -> a -> a

   errors	Control.Error.Util

   An infix form of fromMaybe with arguments flipped.

5. (<<<>:=) :: (MonadState s m, Semigroup r) => LensLike' ((,) r) s r -> r -> m r

   diagrams-lib	Diagrams.Prelude

   (<>) a Semigroup value onto the front of the target of a Lens into your Monad's state and return the old result. However, unlike (<<<>=), it is prepended to the head side. When you do not need the result of the operation, (<>:=) is more flexible.

6. (<<<>:~) :: Semigroup m => LensLike' ((,) m) s m -> m -> s -> (m, s)

   diagrams-lib	Diagrams.Prelude

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

7. (<<>:=) :: (MonadState s m, Semigroup r) => LensLike' ((,) r) s r -> r -> m r

   diagrams-lib	Diagrams.Prelude

   (<>) a Semigroup value onto the front of the target of a Lens into your Monad's state 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.

8. (<<>:~) :: Semigroup m => LensLike ((,) m) s t m m -> m -> s -> (m, t)

   diagrams-lib	Diagrams.Prelude

   (<>) 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.

9. (<>:=) :: (MonadState s m, Semigroup a) => ASetter' s a -> a -> m ()

   diagrams-lib	Diagrams.Prelude

   Modify the target(s) of a Lens', Iso, Setter or Traversal by using (<>). However, unlike <>=, it is prepend to the head side.

10. (<>:~) :: Semigroup b => ASetter s t b b -> b -> s -> t

    diagrams-lib	Diagrams.Prelude

    Modify the target of a Semigroup value by using (<>). However, unlike <>~, it is prepend to the head side.

    >>> ["world"] & id <>:~ ["hello"]
    ["hello","world"]
    

    >>> (["world"], ["lens"]) & _1 <>:~ ["hello"]
    (["hello","world"],["lens"])
