It has come up sporadically over the years, dating back I think to the old Dev Forums before Swift was open-sourced. Best I can find with a quick search of the Evolution list is this message <https://lists.swift.org/pipermail/swift-evolution/Week-of-Mon-20160125/008509.html> from early 2016 where Chris Lattner wrote, “This is a desired feature, but a surprising amount of implementation effort blocks “just doing it”.” So my understanding is that, while it may not be plan-of-record *per se*, it is certainly on the radar.
