Subject: Class method aliased in superclass bypasses subclass overrides

This seems like it should work:

    class Parent
        class << self
            def real_method() "Parent" end
            alias :fake_method :real_method
        end
    end

    class Child < Parent
        def real_method() "Child" end
    end

But it doesn't:

       Child.fake_method # ==> returns "Parent" instead of "Child"

If I replace the alias with a real method definition, e.g.

        def fake_method() real_method end

then it works the way I expect  (Child.fake_method returns "Child").
So what is it about "alias" that bypasses the override?   Do I have to
replace my aliases with extra wrapper methods to get the behavior I'm
looking for?
