A factory method is a method that instantiates an object and returns it. And in a singleton, it must have such a factory method.
So can I say that Singleton pattern is an example of a factory method pattern?
Another example of factory method pattern is of course to return different subclasses of the method's return type.

why bother playing with this "words"? they are for different purposes. It
makes no sense to call a Singleton pattern as a Factory pattern.
