I'm a little confused about this too. I've seen many functions defined like: f x = (\s -> ...) which is a partial function because it returns a function and is the same as: f x s = ...
Off the top of my head the State monad makes extensive use if this style. Is this bad? - deech On 5/2/10, Bradford Larsen <brad.lar...@gmail.com> wrote: > On Sun, May 2, 2010 at 9:18 PM, Edgar Z.
