No you don't.

def f(x):
    return x+1

def g(x):
    return x-1


If I choose to refactor f() and change "x" to "y", why do I care about 
the internal variable inside g()?



Oh wait, I get it... you want to do a global search-and-replace over the 
entire file. *face-palm*

If your functions are less than one-screen full, why do you need a global 
replacement? Global replacement risks changing words in docstrings, 
comments etc that it shouldn't.
