How about a new rule that requires the 'return' statement in a function?

# Class:
def c():
  def __init__(self, spam):
    self.spam = spam

# Function:
def f():
  def __init__(self, spam):
    self.spam = spam
  return

# Null generator:
def g():
  def __init__(self, spam):
    self.spam = spam
  return
  yield None
