You shouldn't notice any difference when calling the function. I was just cleaning up methods that have a self but don't use it.

```` python
>>> class A():
...   def a(self):
...     return 1
...   @staticmethod
...   def b():
...    return 2
... 
>>> x = A()
>>> 
>>> x.a()
1
>>> x.b()  # b can also be called as an instance method
2
