In my enthusiasm to present a tidy code listing I appear to have indented
one statement a little further than I should. I hate mailers that mess with
my layout! The function should have been:

def bin(n):
    l = []
    while n > 0:
        l[:0] = [n%2]
        n /= 2
    if l == [] : return [0]
    return l
