I have not heard such horror stories about Common Lisp (or may be I have forgotten them!). My impression is that python doesn't quite have the kind of {meta,}programming tools Common Lisp has. CL has been used for large critical programs. Perhaps Von Rossum had more experience with statically typed languages than Lisp (because -- pure speculation here -- if he had used CL enough, he would never have designed python :-)
