Who am I: can a class instance determine its own name?

[Harry George]

class MyName:
    #--------------------------
    def init(self,name):
        self.name=name
        try:
            raise None
        except:
            c=sys.exc_info()[2].tb_frame.f_back.f_back
        c.f_locals[name]=self
...

MyName("me")
print me.name
