class CurryingApp a b e | b a -> e, e b -> a whereSource

Methods

(.$.) :: a -> b -> eSource

foo.$.arg curries foo the correct amount and composes it with arg. arg must be of the form a0 -> ... -> aN -> (z0,...,zN1, a0,z0,...zN1,a1,..., aN,z0,...,zNk) foo must be of the form (z0,...,zN1, a0,z0,...zN1,a1,..., aN,z0,...,zNk) -> r .$. has the same fixity as $.
