Whoops. I meant that I'm okay with having sys.implementation.version and sys.implementation.lang_version, both as analogs to sys.version_info. My inclination is to not include the analog to sys.version. However, with the way that you put it, I think you're right that we could put off the lang_version attribute for later. >>> * I've said before that I think the keys in sys.implementation should be >>> locked down (i.e. not writable). >> >>I've been on and off about this.
