Why and how is Lisp better?
CyberFonic: Excellent question, but did you Google for it?  Here's a direct answer:http://itasoftware.com/careers/l_e_t_lisp.html?catid=8and on a more general level Marvin Minsky wrote an excellent paper:http://danreetz.com/ongoing_oversight_and_observation/minsky....Personally, I prefer to 'prototype' things in Python.  And I'm not alone.  E.g. Peter Norvig is one of the top  Lisperati and he has defected to Python.
