2. 1. The fixed point combinator. Called Y in combinatory logic. Fix is a higher-order function which returns a fixed point of its argument (which is a function).

           fix :: (a -> a) -> a
           fix f = f (fix f)

   Which satisfies the equation

           fix f = x such that f x = x.

   Somewhat surprisingly, fix can be defined as the non-recursive lambda abstraction:

           fix = \ h . (\ x . h (x x)) (\ x . h (x x))

   Since this involves self-application, it has an infinite type. A function defined by

           f x1 .. xN = E

   can be expressed as

           f = fix (\ f . \ x1 ... \ xN . E)
             = (\ f . \ x1 ... \xN . E)
                   (fix (\ f . \ x1 ... \ xN . E))
             = let f = (fix (\ f . \ x1 ... \ xN . E))
               in \ x1 ... \xN . E

   If f does not occur free in E (i.e. it is not recursive) then this reduces to simply

           f = \ x1 ... \ xN . E

   In the case where N = 0 and f is free in E, this defines an infinite data object, e.g.

           ones = fix (\ ones . 1 : ones)
                = (\ ones . 1 : ones) (fix (\ ones . 1 : ones))
                = 1 : (fix (\ ones . 1 : ones))
                = 1 : 1 : ...

   Fix f is also sometimes written as mu f where mu is the Greek letter or alternatively, if f = \ x . E, written as mu x . E.
