Nice and compact.  One thing tho, I'm not sure this is the correct way 
to think, but I have an instinct to stay away from 'fancy' commands like 
printf and to rely on native zsh code where possible.  Legit?  Or false 
frugality?  What I half-remember is some loop that has an iteration 
counter.  Mind, there was one of Roman's speed tests where he used an 
external command and had a huge performance improvement, so thereyago.
