Recursive inner function... How?

in this case, the assignment is done by "def":

you're trying to use recursive inner functions ;-)

the easiest fix is to do as Guido intended, and move
"inner" to the global scope.  you can either move the
entire function to the right place, or cheat:

    def outer():
        global inner
        def inner():
            inner()
        inner()

    outer()

(iirc, there's a FAQ entry with more info on this, but the
entire FAQ seems to have disappeared.  a ++Y2K bug?)

btw, also see:
