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.
