-- Hoogle documentation, generated by Haddock -- See Hoogle, http://www.haskell.org/hoogle/ @package test @version 0.0.0 module Bug873 -- | Application operator. This operator is redundant, since ordinary -- application <tt>(f x)</tt> means the same as <tt>(f <a>$</a> x)</tt>. -- However, <a>$</a> has low, right-associative binding precedence, so it -- sometimes allows parentheses to be omitted; for example: -- -- <pre> -- f $ g $ h x = f (g (h x)) -- </pre> -- -- It is also useful in higher-order situations, such as <tt><a>map</a> -- (<a>$</a> 0) xs</tt>, or <tt><a>zipWith</a> (<a>$</a>) fs xs</tt>. -- -- Note that <tt>($)</tt> is levity-polymorphic in its result type, so -- that foo $ True where foo :: Bool -> Int# is well-typed ($) :: () => (a -> b) -> a -> b infixr 0 $ ($$) :: (a -> b) -> a -> b infixr 0 $$
