My question is: did something about the way the special method names are
implemented change for new-style classes?
Just off the top of my head, I'd guess that it's due to classes
already having a default __call__ method,
>>> object.__dict__.keys()
['__setattr__', '__reduce_ex__', '__new__', '__reduce__', '__str__',
'__getattribute__', '__class__', '__delattr__', '__repr__', '__hash__',
'__doc__', '__init__']
No __call__ method here.
used when you instatiate.
The __call__ method used to instanciate a class is actually the
metaclass __call__ method.
>>> class MyType(type):
... def __call__(self, *args, **kw):
... print "pikaboo"
... return type.__call__(self, *args, **kw)
...
>>> class MyClass(object):
... __metaclass__ = MyType
...
>>> MyClass()
pikaboo
<__main__.MyClass object at 0x8334eec>
