Because I do like recursion, and would personnally prefer tail-recursion 
optimisation over nice tracebacks. But I'm not in position to decide 
anything here.

Yes. And everything done with Python can be done with assembly language 
too.

Recursion is the most convenient way to express some common algorithms. 
Too bad for you if it does some nasty things to your mind.
