You are right about the runtimes. SBCL is something else. And there have been attempts to pull Python into Lisp: http://common-lisp.net/project/python-on-lisp/

You are right about the runtimes. SBCL is something else. And there have been attempts to pull Python into Lisp: http://common-lisp.net/project/python-on-lisp/ http://common-lisp.net/project/python-on-lisp/ The only thing is, I find CL a really baroque language. The issues have been touched upon by many, but CL just has many spots where due to being standardized 2 decades ago, it isn't really consistent. Python for the most part is extremely consistent and the VM runs on any major OS (SBCL still has issues on Windows). Not to mention the language seems to be evolving naturally (Python 3). That's the main reason I'd like to see a Lisp on Python.
