Released Python 2 methods that act like unbound methods from Python 3. You can actually call them without an instance.
Normal Python 2 behavior:
>>> class MyClass(object):
... def my_method(self):
... return self
>>> MyClass.my_method(1)
Traceback (most recent call last):
...
TypeError: unbound method my_method() must be called with MyClass instance
as first argument (got int instance instead)
Released behavior:
>>> from released import object
>>> class MyClass(object):
... def my_method(self):
... return self
>>> # An instance method like before.
>>> my_instance = MyClass()
>>> my_instance.my_method
<bound method MyClass.my_method of <MyClass object at ...>>
>>> my_instance.my_method()
<MyClass object at ...>
>>> # As a released class method.
>>> MyClass.my_method
<function my_method at ...>
>>> MyClass.my_method(1)
