I'd be more than happy to hear your arguments. Perhaps I am missing some points you could show me clearly? Your original post lacked some explanation behind what you mean by word hacking itself and while at first kind of dismissed your post with ESR, I would like to know what do you think hacking is about? (As esr's text guided me somehow, your comment made me think i may actually be missing something)
I think that starting with both Python and Ruby is
a bit strange idea - they are really similar (in almost
every way I can think of)
Exactly the point. They are so similar that the transition from one to the next is easier than most other languages. Once you have an easy transition students will notice similar patterns. "Oh, looping. Hey, this is something that happens in both languages."
