There is nothing special about the LeoApp class. It simply gets instantiated once. Some people consider singleton's to be bad design. I agree, if that means that being a singleton actually affects the class's code. In particular, a singleton class that uses static methods (without self) is asking for big trouble. That's why I am willing to go to so much trouble to have @cmd decorators be able to "reconstitute" the self argument. Methods that implement Leo commands must be first-class methods of their class, not "self-less" functions. Many commands use self!
