Yes, I know that. That's why I asked about the relation between ast.txt and Python.adsl. If internally the parser uses the .adsl, but expose as a reflection mechanism things that were generated from ast.txt, then there could be a mismatch. Where does ast.txt comes from ? Shouldn't it be generated itself from Python.adsl ? So we would have Python.adsl ----????----> ast.txt ---- astgen.py ---> ast.py containing all the UnarySub, Expression, classes that represents a Python AST. > > HTH, > Martin _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
