Before cons'ing the result of init', you should check whether it's Just or Nothing. What you're doing now is something along the line with 5 : Just 3 -- this won't typecheck. On Tue, May 12, 2015 at 5:22 PM Roelof Wobben <r.wobben@home.nl> wrote:

I do not understand what you are saying to me.
I know that init produces a Maybe [a] . That is why I did put a Just before it.
You are invoking it again though, and using its result as if it produces [a] instead of Maybe [a].

What is then the right way to do. I still do not understand what you are trying to make clear to me.
