That's a good suggestion. Unfortunately, "derivative work" is an established legal term, and was before the GPL, so I don't think I should use it. In fact, it should be part of my definition, now that I think about it. However, if I can come up with some other term, then I'll definitely take your suggestion. I'll just define it to be "this software," any derivative work, or the application of an algorithm...and then make the license apply to that definition. I hope that makes sense and is what you meant. If not, please let me know.
