When someone comes looking at a program like this, s/he can see
exactly what depends on what. There can be exceptions, of course
(sometimes mutual recursion really is the right thing to do,
especially with tree-walking routines), but those can then be noted
with comments ("Mutually recursive with xyz()."), or in some cases may
be obvious from the names. In any case, the bulk of most programs can
be written in this style, and it does improve clarity.
Hope that's of value. Like all advice, it's just one person's opinion,

I'd argue that Python has assignment, and assignment in Python is
identical with binding references to objects.
