Personally I don't think recursion is a problem in this context. 
You would need a pretty dumb user to get it wrong 1000 times 
(Pythons default recursion limit). So although a loop is the 
more pythonic idiom a recursive solution here is fine in my 
personal view.

But that may just be because I'm (yet again) playing with Lisp
and therefore thinking recursively about problems rather 
than thinking loops.
