For the following code:

class A(object):

    def __init__(self):

        self.a = True

    def method(self):

        if not self.a:
            test = 1
            dest = test + 2
        else:
            # UnboundLocalError: local variable 'test' referenced before assignment
            dest = test + 3
            test = 1


if __name__ == "__main__":
    a = A()
    a.method()

Maybe we can detect that test is conditionally defined.
