Well, you can do it with the existing recursion in Haskell
let yc f = f (yc f)
Or you can encode it with type level recursion and no value recursion
by using a recursive data type.

Hi,
Writing
yc = \f -> (\x -> f(x x)) (\x -> f(x x))
causes type error. Is there a way to define it in Haskell?
Thanks,
Haihua
