You might be interested in EasyExtend: http://www.fiber-space.de/EasyExtend/doc/EE.html Unlike Logix there are no macros defined in application code and there are no runtime macro expansions. So extension language semantics is always fixed at compile time. > Personally, I would like to see macros in Python (actually Logix > succeeding is good enough).

Although Logix was written in Python and compiled to CPython bytecodes it was a language on its own right: a Python / Lisp hybrid. Opposed to this EasyExtend is a Python framework for language extensions and not itself a language. A quite typical use case may not involve any new grammar rules or terminals, but just generates code. See the coverage fiber as an example. -- http://mail.python.org/mailman/listinfo/python-list
