Manlio,
We live in the age of participation -- of co-education. Don't worry about
text-books. Contribute to some wiki pages & blogs today that share these
smart techniques with others.
<twocents>Learning/progress is mainly results when people respond to their
own incomprehension by moving into new & challenging ideas, not by banishing
them. Puzzlement can be met by resistance or by embracing &
learning.</twocents>

However, ironically, I stopped using them for pretty
much the same reason that Manlio is saying.
Are you saying there's a problem with this implementation? It's the only one I could just read immediately.
Yes, you understand it immediately once you know what a state monad is. But how well is introduced, explained and emphasized the state monad in current textbooks?
When I started learning Haskell, the first thing I learned was recursion and pattern matching.
So, this may be the reason why I find more readable my takeList solution.
