    Hmmm...  I am singularly unconvinced that I can accept this as
 a proper excuse.  However, since I can not wield a whip at this
 distance, I suppose I will have to just allow it.  Did you take a
 look at the step-up module I did.  It popped out all by itself.
 I noted that Excel has a rounded step-up function a bit earlier,
 and wondered briefly how they accomplished it, and consigned it
 to the depths of unconsciousness thereafter.  When the question
 came up, an answer just popped up from out of the soup.  Neat.
 There is no problem so complex that a nap can't help.
