You and Aahz maybe, but now we've got a fight <wink>.  There's nothing
un-Pythonic about recursion, tail or otherwise.  It's tail-call
*optimization* that's un-Pythonic, as it's a gimmick supported by only a
handful of widely unused <0.5 wink> languages and surprising to people
coming from anything else:  damaging tracebacks would be Major Badness, much
worse than the gain for the relative thimbleful of people who are
uncomfortable coding loops etc.
