I suspect we’re going to collect a number of “good and approved ideas, but which do not have someone signed up to code it up in the compiler”.  This may end up being the difference between something getting into Swift 3 or not.

Will there be a distinct status for such proposals?  It might be nice to do this so prospective contributors to the compiler have a place to find “ready to go” projects if they’re interested in working on new features.
