It's much more attractive, because it doesn't change the function
signature. In fact, here's a variation that doesn't even need a
language change::
>>> class Foo(object):
... def __init__(self, spam, eggs, beans):
... self.__dict__.update(dict(
... (name, value) for (name, value) in vars().items()
... if name in ['spam', 'beans']))
...
>>> foo = Foo("some spam", "more eggs", "other beans")
>>> foo.spam
'some spam'
>>> foo.eggs
Traceback (most recent call last):
File "<stdin>", line 1, in ?
AttributeError: 'Foo' object has no attribute 'eggs'
>>> foo.beans
'other beans'
