-- | This small library defines data types 'Tup1', 'Tup2' ... 'Tup9' for homogeneous tuples of small size (both strict and lazy),
-- and various instances for them, most notably 'Functor' and 'Applicative'. We also have a 'Tup' type class:
--
-- > class Tup f where
-- > tupSize :: f a -> Int
-- > tupToList :: f a -> [a]
-- > tupFromList :: [a] -> f a
-- > tupProxy :: f a -> Proxy a
-- > ...
--
-- Also included is a very simple preprocesszor @tuplepp@ which translates
-- the syntax @\{\{a,b,c\}\}@ into @(Tup3 a b c)@.
--
-- A different implementation is also given in the module "Data.Tup.Vec"; this basically implements
-- lists which encode their length in their types. For this, just replace 'Tup' by 'Vec' everywhere.
-- The same instances and functions are provided.
--
-- A third implementation is in "Data.Tup.Newtype"; here the tuples are newtypes of Haskell tuples.
-- Just replace 'Tup' by 'NTup'.
