The impression that I have (from a distance) is that Pyparsing is a good interface abstraction with a kludgy and slow implementation. That the implementation uses regexps just goes to show how kludgy it is. One hopes that someday there will be a more serious implementation, perhaps using llvm-py (I wonder whatever happened to that project, by the way) so that your parser script will compile to executable machine code on the fly. -- http://mail.python.org/mailman/listinfo/python-list
