Yes, of course, I had overlooked that point.

Well, I had realized that the arbitrary integers could (and probably might
be) different; I guess I just wanted a more elegant way than that currently
implemented, such as the time honoured use of "m" and "n" in such situations.
I had overlooked the fact that "n" (and "m" as well of course) might well be
defined already by the user, and although I take your points entirely, I'm
still left with the feeling that a more elegant solution exists.
