silly example that shows how python classes are really just sugar for the simple cases

class_without_class.py

def Blank():
    # this is a hacky way of returning an empty
    # object that you can set attributes on, without
    # having to create a class
    return lambda: None

def klass(factory):
    def init(*args):
        self = Blank()
        
        def method(method_name):
            def decorate(f):
                setattr(self, method_name, f)
                return f
            return decorate

        return factory(self, method, *args)
    return init


@klass
def Person(self, method, name, salary):
    self.name = name
    self.salary = salary

    @method('give_raise')
    def _():
        self.salary *= 1.1

    return self

alice = Person('alice', 100)
bob = Person('bob', 200)
print alice.name
alice.give_raise()
print alice.salary
print bob.name
