The version-requirement should denominate the version such that the program *can't work* with versions below this; not that some features may be less convenient than without this version. Your suggestion helps with backward-compatibility of GO::L with older scripts; not with backward-compatibility of scripts with older GO::L. IlyaThread Previous | Thread Next
