just a few quick observations comming from an imperative background, I found point free code very difficult to understand when learning Haskell. It is not that it is hard to understand the concepts of point-free style, it is that it is hard to know when something is point-free. It is "another option" and I think the best way to make a language "readable" is to stick to a few simple rules and clean semantics. Since, you can't write all your code point-free, I say write it all pointed - consistency is the thing! also, the term "point free" confused me for quite a while. Point-free code has lots of points (periods) and so I kept thinking it was the other way around. matt On 11/02/2005, at 7:19 AM, Henning Thielemann wrote:

Now compare that to the following function, which does the some thing but without point-free notation:
incrEach' :: Integer -> [Integer] -> [Integer] incrEach' i is = is >>= \i' -> return (i'+i)
point-free again
is >>= return . (i+)
