We should not discard the scalar in scalar*infinity expressions.
I don't think that would help as much as you seem to imagine it would. Consider f(x) = 1/x**2, g(x) = 1/x**3, h(x) = f(x) / g(x). Keeping a scalar multiplier attached to infinities isn't going to help you get a sensible result for h(0) given f(0) and g(0). Doing that kind of thing would require a full-blown computer algebra system capable of reasoning about limits. -- Greg
