In some ways that's even cleaner.
In my simplivied example all the foo() method was doing was
setting/returning an attribute, but usually there's a bit more
going on (e.g. system calls with possible side effects).
To me it's a bit more explicit that
d.foo(3)
d.foo()
are doing something other than just getting/setting the value
of an instance attribute. If all I really wanted to do was
get/set the instance's "v" attribute, I probably would have
just done it like this
d.v = 3
print d.v
