This is false. For instance:
class A(object):
def method(self, a):
print a
class B(A):
def method(self, a, b):
print a, b
B implements a different interface than A. Statically typed OO
languages either use multi-methods or disallow changing the signature
of an overridden method.
A tool to detect such cases would probably be almost as useful as the
tool you've proposed.
