This isn't a fundamental problem, since you can always declare a
private function if it's mutually recursive with another private
function. But - forgive me if this is false in CPython - this isn't
usually that common. Also, ordering the functions in (at least an
approximation of) Define Before Use makes it easy to locate the one
you're calling, even in a non-smart editor: just go to the top of the
file and search for the function's name; the first hit will be the
definition. It's not usually difficult to sort functions
appropriately, and can pay dividends in readability.
