1. newtype Dual a

   base	Data.Monoid

   The dual of a Monoid, obtained by swapping the arguments of (<>).

   Dual a <> Dual b == Dual (b <> a)
   

   Examples

   >>> Dual "Hello" <> Dual "World"
   Dual {getDual = "WorldHello"}
   

   >>> Dual (Dual "Hello") <> Dual (Dual "World")
   Dual {getDual = Dual {getDual = "HelloWorld"}}
   

2. Dual :: a -> Dual a

   base	Data.Monoid

   No documentation available.

3. newtype Dual a

   base	Data.Semigroup

   The dual of a Monoid, obtained by swapping the arguments of (<>).

   Dual a <> Dual b == Dual (b <> a)
   

   Examples

   >>> Dual "Hello" <> Dual "World"
   Dual {getDual = "WorldHello"}
