The Python urllib/urllib2 issue is a feature. It means any code that uses the old (inferior) urllib continues to work, without having to update it as urllib2 starts being used within the same function so that it can be migrated. That's what promising stability means. This applies to your last paragraph as well -- I do want to be using code that folks are trusting to be the way to do things forever (well, at least for a few years). I'm not trying to learn yet another CADT language / ecosystem. Also note that both crates mentioned in this subthread (regex and rand) are at version 0.x; to a not-really-a-rust-person like me, it signals "experimental API, avoid avoid avoid". I assume that is the reason to start a concerted effort to get everything to 1.0 levels. (I'm mostly commenting because the roadmap under discussion seems to be heading towards the sort of promised stability that I want to see; so having somebody known to be rather close to rust development saying the exact opposite rather unsettles me. Sorry.)
