People coming from functional languages like Lisp and Haskell often say that, but how many recursive algorithms naturally take a tail-call form? Not that many.
And the ones that do tend to be the ones that are better expressed iteratively in Python. So Python doesn't really need tail call optimisation. Also, Guido has said that he doesn't like it, because of the detrimental effect it has on stack tracebacks. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
