Please don't use the term "class variables" to mean class *attributes*,
it makes my brain hurt. If a string variable is a string, and an int
variable is an int, and a bool variable is a bool, a class variable
should be a class.
What you can do is shift the creation of the class attribute to the
constructor, instead of when the class is created:
def __init__(self, bar_init):
self.__class__.foo = bar_init
But I'm not sure why you would want to.
