Dealing with recursive functions that are only called by themselves

[johndoknjas]

def Rec():
    Rec()

class MyClass:
    def __init__(self):
        pass

    def classRec():
        MyClass.classRec()

For this code snippet, vulture doesn't label any of the functions as unused, even though their only calls are to themselves. So to see if a function is used, I'd propose not considering recursive calls.
