  Options aren't typically passed to "code".  They're passed to the main
function of a program.  For example:

    def main(argv):
        o = GameOptions()
        o.parse(argv[1:])
        ...

  If your code is structured like this, you can avoid using eval() and exec
altogether and simply import and call the main function:

    from foo import main
    main(['progname', '-w'])

  Hope this helps,
