I've written some class which allows me to derive from it to make objects lazy instantiated. Do you see notational improvements or maybe even cases where this method might not work (multiple inheritance etc.)? What else could I try? Here is the code

    class LazyProxy(object):
        def __init__(self, cls, *params, **kwargs):
            self.__dict__["_cls"]=cls
            self.__dict__["_params"]=params
            self.__dict__["_kwargs"]=kwargs
    
            self.__dict__["_obj"]=None
    
        def __getattr__(self, name):
            if self.__dict__["_obj"] is None:
                self.__init_obj()
    
            return getattr(self.__dict__["_obj"], name)
    
        def __setattr__(self, name, value):
            if self.__dict__["_obj"] is None:
                self.__init_obj()
    
            setattr(self.__dict__["_obj"], name, value)
    
        def __init_obj(self):
            self.__dict__["_obj"]=object.__new__(self.__dict__["_cls"], *self.__dict__["_params"], **self.__dict__["_kwargs"])
            self.__dict__["_obj"].__init__(*self.__dict__["_params"], **self.__dict__["_kwargs"])
    
    
    class LazyInit(object):
        def __new__(cls, *params, **kwargs):
            return LazyProxy(cls, *params, **kwargs)
    
    
    class A(LazyInit): # classes meant to be lazy loaded are derived from LazyInit
        def __init__(self, x):
            print("Init A")
            self.x=14+x
    
    a=A(1)
    print("Go")
    print("15=", a.x)
