For example, F requires one to do this when using nested modules so that variables are not propagated in long chains through modules (deemed not good for education). There will always be compiler errors when compiling these intricate matters. But if there is no compelling reason to do otherwise, include the USE M1 explicitly. I always to this to avoid confusion. I am not willing to search the standard on this, and the "F95 Handbook" did not seem to give a precise answer. But I remember seeing the above stated in some book as a way of hiding USEd modules.
