1. (>$<) :: Contravariant f => (a -> b) -> f b -> f a

   incipit-base	Incipit.Base

   This is an infix alias for contramap.

2. (|$|) :: Semigroup t => (a -> b) -> a -> PerfT IO t b

   perf	Perf.Types

   lift a pure, unnamed function application to PerfT

3. (***$) :: Profunctor p => (b -> c) -> p a b -> p a c

   product-profunctors	Data.Profunctor.Product

   ***$ is the generalisation of Functor's <$>. ***$ = rmap, just like <$> = fmap. (You probably won't need to use this. <$> should be sufficient.) Since 0.11.1.0: Generalised to work on arbitrary Profunctors.

4. (***$) :: Profunctor p => (b -> c) -> p a b -> p a c

   product-profunctors	Data.Profunctor.Product

   ***$ is the generalisation of Functor's <$>. ***$ = rmap, just like <$> = fmap. (You probably won't need to use this. <$> should be sufficient.) Since 0.11.1.0: Generalised to work on arbitrary Profunctors.

5. (!$) :: Match a -> CaptureID -> Capture a

   regex	Text.RE.Replace

   an alternative for capture

6. (!$$) :: Match a -> CaptureID -> a

   regex	Text.RE.Replace

   an alternative for captureText

7. (!$$?) :: Match a -> CaptureID -> Maybe a

   regex	Text.RE.Replace

   an alternative for captureTextMaybe

8. (!$?) :: Match a -> CaptureID -> Maybe (Capture a)

   regex	Text.RE.Replace

   an alternative for capture captureMaybe

9. (.$) :: forall (l :: Symbol) (r' :: Row Type) t (r :: Row Type) x . (KnownSymbol l, (r' .! l) ≈ t) => (Rec ((l .== t) .+ r) -> x) -> (Label l, Rec r') -> Rec r -> x

   row-types	Data.Row.Records

   This function allows one to do partial application on a function of a record. Note that this also means that arguments can be supplied in arbitrary order. For instance, if one had a function like

   xtheny r = (r .! #x) <> (r .! #y)
   

   and a record like

   greeting = #x .== "hello " .+ #y .== "world!"
   

   Then all of the following would be possible:

   >>> xtheny greeting
   "hello world!"
   

   >>> xtheny .$ (#x, greeting) .$ (#y, greeting) $ empty
   "hello world!"
   

   >>> xtheny .$ (#y, greeting) .$ (#x, greeting) $ empty
   "hello world!"
   

   >>> xtheny .$ (#y, greeting) .$ (#x, #x .== "Goodbye ") $ empty
   "Goodbye world!"
   

10. (<$:) :: (CFunctor f, Dom f a, Dom f b) => a -> f b -> f a
