1. (+:) :: a -> a -> Complex a

   numhask	NumHask

   Complex number constructor. Internally, Complex derives most instances via EuclideanPair. For instance,

   >>> sqrt (1.0 +: (-1.0)) :: Complex Double
   Complex {complexPair = (1.0986841134678098,-0.45508986056222733)}
   

   >>> sqrt ((-1.0) +: 0.0) :: Complex Double
   Complex {complexPair = (6.123233995736766e-17,1.0)}
   

2. (+:) :: a -> a -> Complex a

   numhask	NumHask.Data.Complex

   Complex number constructor. Internally, Complex derives most instances via EuclideanPair. For instance,

   >>> sqrt (1.0 +: (-1.0)) :: Complex Double
   Complex {complexPair = (1.0986841134678098,-0.45508986056222733)}
   

   >>> sqrt ((-1.0) +: 0.0) :: Complex Double
   Complex {complexPair = (6.123233995736766e-17,1.0)}
   

3. (<:>) :: HeaderName -> ByteString -> MatchHeader

   sydtest-wai	Test.Syd.Wai

   No documentation available.

4. (<:>) :: HeaderName -> ByteString -> MatchHeader

   sydtest-wai	Test.Syd.Wai.Matcher

   No documentation available.

5. (&:) :: forall x (xs :: [Type]) . x -> HList xs -> HList (x ': xs)

   tmp-proc	System.TmpProc.Docker

   An infix alias for HCons.

6. (&:&) :: x -> y -> HList '[x, y]

   tmp-proc	System.TmpProc.Docker

   An infix alias for both.

7. (&:) :: forall x (xs :: [Type]) . x -> HList xs -> HList (x ': xs)

   tmp-proc	System.TmpProc.TypeLevel

   An infix alias for HCons.

8. (&:&) :: x -> y -> HList '[x, y]

   tmp-proc	System.TmpProc.TypeLevel

   An infix alias for both.

9. (.:) :: FromYAML a => Mapping Pos -> Text -> Parser a

   HsYAML	Data.YAML

   Retrieve value in Mapping indexed by a !!str Text key. This parser fails if the key doesn't exist.

10. (.:!) :: FromYAML a => Mapping Pos -> Text -> Parser (Maybe a)

    HsYAML	Data.YAML

    Retrieve optional value in Mapping indexed by a !!str Text key. Nothing is returned if the key is missing. This combinator only fails if the key exists but cannot be converted to the required type. NOTE: This is a variant of .:? which doesn't map a tag:yaml.org,2002:null node to Nothing.
