These aren't mutually exclusive ideas. While I'm sure there's many ways we could solve this problem, David's idea has the distinct advantage of being dead simple. I'd rather not block his vision on some other large refactor that may never materialize. (And
if it _does_ materialize, we could revert any wiring-in of Coercible quite easily.)<o:p></o:p></p>
