The following test asserts on mozilla-central revision 19bfe36cace8 (options -m -n -a): function loop( p = 1, actual = this) { for (var i = 0; (function() { actual += this.assertEq + ' toString, '; }); ++i) { } }
Oops, the assert is overly conservative: the heavyweight flag can be set later in rare cases, but the only important thing is that it gets set. On a side note, the way the heavyweight flag gets set (and closed vars get noted) is pretty awkward.
