Hi Alex, OK thx.
For some examples it isn't clear how they should be run. They are not "ready to run" straight away. Since I try to make the examples approachable, I strive to also give the code (and/or data) to make such examples work. In this case I guessed that the example could use STDIN. But I understand your explanation.
