You don't need to. The reason why you need to "declare" variable when
doing something like a += 1 is because this is actually a shorthand
for a = a + 1 (unless you override __radd__), the a on the right-hand
side is not yet assigned to any objects (remember that python use the
"name tag" model instead of "variable" model).
