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.
