yes, one more gentle haskell introduction LOL

i think that this is one more example of pattern where we suggest to
beginner advanced solution of problem. of course, problem still
exists and from time to time we need to solve it. but ABSOLUTELY MOST
of cases where beginners try to do something like this is when they
don't groked FP programming style and try to use Haskell in the
imperative way

so, Phlex, don't listen to my opponents :)  solution they suggest is
not what you need nor that you can understand now
