1. (.|) :: OnObject o a => o a -> a -> o a

   json-stream	Data.JsonStream.Parser

   Return default value if the parsers on the left hand didn't produce a result.

   p .| defval = p <|> pure defval
   

   The operator works on complete left side, the following statements are equal:

   Record <$>  "key1" .: "nested-key" .: value .| defaultValue
   Record <$> (("key1" .: "nested-key" .: value) .| defaultValue)
   

2. (.|.) :: Bits a => a -> a -> a

   base	Data.Bits

   Bitwise "or"

3. (.|.) :: Bits a => a -> a -> a

   base	GHC.Bits

   Bitwise "or"

4. (.||.) :: (Testable prop1, Testable prop2) => prop1 -> prop2 -> Property

   QuickCheck	Test.QuickCheck

   Disjunction: p1 .||. p2 passes unless p1 and p2 simultaneously fail.

5. (.||.) :: (Testable prop1, Testable prop2) => prop1 -> prop2 -> Property

   tasty-quickcheck	Test.Tasty.QuickCheck

   Disjunction: p1 .||. p2 passes unless p1 and p2 simultaneously fail.

6. (.|.=) :: (MonadState s m, Bits a) => ASetter' s a -> a -> m ()

   lens	Data.Bits.Lens

   Modify the target(s) of a Lens', Setter or Traversal by computing its bitwise .|. with another value.

   >>> execState (do _1 .|.= 15; _2 .|.= 3) (7,7)
   (15,7)
   

   (.|.=) :: (MonadState s m, Bits a) => Setter' s a    -> a -> m ()
   (.|.=) :: (MonadState s m, Bits a) => Iso' s a       -> a -> m ()
   (.|.=) :: (MonadState s m, Bits a) => Lens' s a      -> a -> m ()
   (.|.=) :: (MonadState s m, Bits a) => Traversal' s a -> a -> m ()
   

7. (.|.~) :: Bits a => ASetter s t a a -> a -> s -> t

   lens	Data.Bits.Lens

   Bitwise .|. the target(s) of a Lens or Setter.

   >>> _2 .|.~ 6 $ ("hello",3)
   ("hello",7)
   

   (.|.~) :: Bits a             => Setter s t a a    -> a -> s -> t
   (.|.~) :: Bits a             => Iso s t a a       -> a -> s -> t
   (.|.~) :: Bits a             => Lens s t a a      -> a -> s -> t
   (.|.~) :: (Monoid a, Bits a) => Traversal s t a a -> a -> s -> t
   

8. (.|.) :: JExpr -> JExpr -> JExpr

   ghc	GHC.JS.Make

   JS infix bit operators

9. (.||.) :: JExpr -> JExpr -> JExpr

   ghc	GHC.JS.Make

   JS infix bit operators

10. (.|.) :: Bits a => a -> a -> a

    ghc	GHC.Prelude.Basic

    Bitwise "or"
