This may be a bit of the topic but would support for in-lining be
acceptable or even just close interoperability of the two languages.
Python and Lisp are similar but some pieces of code are more easily
implemented in one or the other. Maybe something like:
(LISP CODE)
(LISP CODE)
:@python
python code
python code
:@PYTHON
(LISP CODE)
(LISP CODE)
