1. ($$) :: Doc -> Doc -> Doc

   pretty	Text.PrettyPrint

   Above, except that if the last line of the first argument stops at least one position before the first line of the second begins, these two lines are overlapped. For example:

   text "hi" $$ nest 5 (text "there")
   

   lays out as

   hi   there
   

   rather than

   hi
   there
   

   $$ is associative, with identity empty, and also satisfies
   • (x $$ y) <> z = x $$ (y <> z), if y non-empty.

2. ($+$) :: Doc -> Doc -> Doc

   pretty	Text.PrettyPrint

   Above, with no overlapping. $+$ is associative, with identity empty.

3. ($$) :: Doc a -> Doc a -> Doc a

   pretty	Text.PrettyPrint.Annotated

   Above, except that if the last line of the first argument stops at least one position before the first line of the second begins, these two lines are overlapped. For example:

   text "hi" $$ nest 5 (text "there")
   

   lays out as

4. ($+$) :: Doc a -> Doc a -> Doc a

   pretty	Text.PrettyPrint.Annotated

   Above, with no overlapping. $+$ is associative, with identity empty.

5. ($$) :: Doc a -> Doc a -> Doc a

   pretty	Text.PrettyPrint.Annotated.HughesPJ

8. ($+$) :: Doc -> Doc -> Doc

   pretty	Text.PrettyPrint.HughesPJ

   Above, with no overlapping. $+$ is associative, with identity empty.

9. ($!) :: (a -> b) -> a -> b

   hedgehog	Hedgehog.Internal.Prelude

   Strict (call-by-value) application operator. It takes a function and an argument, evaluates the argument to weak head normal form (WHNF), then calls the function with that value.

10. ($>) :: Functor f => f a -> b -> f b

    semigroupoids	Data.Functor.Apply

    Flipped version of <$.

    Examples

    Replace the contents of a Maybe Int with a constant String:

    >>> Nothing $> "foo"
    Nothing
    

    >>> Just 90210 $> "foo"
    Just "foo"
    

    Replace the contents of an Either Int Int with a constant String, resulting in an Either Int String:

    >>> Left 8675309 $> "foo"
    Left 8675309
    

    >>> Right 8675309 $> "foo"
    Right "foo"
    

    Replace each element of a list with a constant String:

    >>> [1,2,3] $> "foo"
    ["foo","foo","foo"]
    

    Replace the second element of a pair with a constant String:

    >>> (1,2) $> "foo"
    (1,"foo")
