I often write code like:

class MyClass:
    def __init__(self, attr1=None, attr2=None, attr3=None):
        self.attr1 = attr1   # I interpret "None" as "uninitialized".
        self.attr2 = attr2
        self.attr3 = attr3

If you absolutely must pass in a dictionary, you can use

instance = apply(MyClass, (), {'attr1': 1, 'attr2': 2, 'attr3': 3})

using the third argument to apply.

If the case of keywords is wrong, an TypeError will be raised.

Is this good enough?
