  > instance Default a => Default (Const a b) where
  >     def = Const def
  >
  > instance Monad m => Default (Kleisli m a b) where
  >     def = Kleisli return
  >
  > instance Default Version where
  >     def = Version [] []
  .
  Following instances are available only for base >= 4.7.0.0:
  .
  > instance Default (Proxy a) where
  >     def = Proxy
  >
  > instance Default SomeNat where
  >     def = SomeNat (Proxy :: Proxy 0)
  >
  > instance Default SomeNat where
  >     def = SomeSymbol (Proxy :: Proxy "")
  .
  Following instances are available only for base >= 4.8.0.0:
  .
  > instance Alternative f => Default (Alt f a) where
  >     def = Alt empty
  >
  > instance Default a => Default (Identity a) where
  >     def = Identity def
  >
  > instance Default Natural where
  >     def = 0
  .
  Following instances are available only for base >= 4.9.0.0:
  .
  > instance Default a => Default (NonEmpty a) where
  >     def = def :| []
  >
  > instance Bounded a => Default (Min a) where
  >     def = minBound
  >
  > instance Bounded a => Default (Max a) where
  >     def = maxBound
  >
  > instance Default (Option a) where
  >     def = Option Nothing
