Why wouldn't Bulat's version work?

I don't think it will work for me either way as I'm returning m (Maybe Int) where m is my own monad. It seems that folks assumed that m itself was the maybe monad. Unless I'm mistaken the code below won't work otherwise.

must also work :)

But it won't.
I have made this mistake too in the past ;-)
