-- concatenation of results using function composition.
type ShowS = String -> String

-- | Conversion of values to readable 'String's.
--
-- Derived instances of 'Show' have the following properties, which
-- are compatible with derived instances of 'Text.Read.Read':
--
-- * The result of 'show' is a syntactically correct Haskell
--   expression containing only constants, given the fixity
--   declarations in force at the point where the type is declared.
--   It contains only the constructor names defined in the data type,
--   parentheses, and spaces.  When labelled constructor fields are
--   used, braces, commas, field names, and equal signs are also used.
--
-- * If the constructor is defined to be an infix operator, then
--   'showsPrec' will produce infix applications of the constructor.
--
-- * the representation will be enclosed in parentheses if the
--   precedence of the top-level constructor in @x@ is less than @d@
--   (associativity is ignored).  Thus, if @d@ is @0@ then the result
--   is never surrounded in parentheses; if @d@ is @11@ it is always
--   surrounded in parentheses, unless it is an atomic expression.
--
-- * If the constructor is defined using record syntax, then 'show'
--   will produce the record-syntax form, with the fields given in the
--   same order as the original declaration.
--
-- For example, given the declarations
--
-- > infixr 5 :^:
-- > data Tree a =  Leaf a  |  Tree a :^: Tree a
--
-- the derived instance of 'Show' is equivalent to
--
-- > instance (Show a) => Show (Tree a) where
-- >
-- >        showsPrec d (Leaf m) = showParen (d > app_prec) $
-- >             showString "Leaf " . showsPrec (app_prec+1) m
-- >          where app_prec = 10
-- >
-- >        showsPrec d (u :^: v) = showParen (d > up_prec) $
-- >             showsPrec (up_prec+1) u .
-- >             showString " :^: "      .
-- >             showsPrec (up_prec+1) v
-- >          where up_prec = 5
--
-- Note that right-associativity of @:^:@ is ignored.  For example,
--
-- * @'show' (Leaf 1 :^: Leaf 2 :^: Leaf 3)@ produces the string
--   @\"Leaf 1 :^: (Leaf 2 :^: Leaf 3)\"@.
