It's not too big a change from ES3.1-strict, but it may be too late. If it's
not too late, I would be in favor of this change. (I have previously
advocated this change on es-discuss.) Note that
Number.prototype.box = function() {
"use strict";
return this;
}
var n = (42).box.call(42);
will correctly do what you want in ES3.1, so it seems a shame if we can't
fix the simpler form.
