That sounds somewhat puzzling as units cannot really propagate without them somehow telling how they would change! (e.g., the outcome of sin(a) is possible only for angular units and then depends on that unit). But in any case, the mailing list is probably not the best case to discuss this - rather, I look forward to -- and will most happily give feedback on -- a NEP or other more detailed explanation!
