[Haskell-cafe] Re: Point-free style

[Matthew Roberts]

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.
