Once people know that they /can/ get it if they want, they no longer want it. What doesn't make sense is writing entire language implementations from scratch in order to experiment with notations. I think someone may have been working on a Python interface built on Common Lisp. Ah, here! http://trac.common-lisp.net/clpython/wiki/WikiStart -- http://mail.python.org/mailman/listinfo/python-list
