Ah, thanks for the correction.

I just tried out your stepper (which I'll refer to as `cl-stepper')
and it provides exactly the sort of experience I was hoping for. More
people need to try it - IMHO cl-stepper provides a *much better*
debugging experience than what you get out-the-box, even with SLIME
goodies like stack inspection etc. Being able to step through my code
probably just saved me *hours* of pain. Thank You M. Bourguignon!
