Actually theres soo much in common lisp besides macros that i miss in addition to them when i have to work with python, like CLOS, the condition system, format, the lisp reader/printer(using JSON is only half a solution), good performance, and with paredit mode for emacs i can edit code a lot easier than with python.

Also your summary, python and ruby's libraries are not free, because you have to use python or ruby instead of common lisp. That is a cost of some kind, a trade off, is it not?
