I am pretty sure such a context-dependent rule cannot be written as a context-free grammar rule. In any case, the function object does not exist when code is being compiled to a code object. So this requires implementation-dependent post-patching of the code object. R. Hetchinger(sp?) posted a Cookbook recipe for doing this for CPython. Anyone wanting the speedup (with CPython) can use it. tjr -- http://mail.python.org/mailman/listinfo/python-list
