Could someone advise on whether it still makes sense to spend time on this proposal? Or is this part of Swift too solidified to change at this point?

1) get some consensus on list for an overall approach
2) formalize a proposal and submit a PR to swift-evolution
3) iterate

#1 is the hardest I think.  I don’t think a truly minimal wrapper of the POSIX APIs is interesting, I think we should at least make a Swifty POSIX API, which is portable and low-abstraction overhead.  However, it should fix the mistakes of errno and “creat” among other things.
