New issue 2673 by vego...@chromium.org: Profiler way of marking function
for recompilation is not good for mixin class pattern
http://code.google.com/p/v8/issues/detail?id=2673
In the code below V8 will never optimize function length because it marks
individual closure instances that are never used again:
function Point(x, y) {
this.x = x;
this.y = y;
this.length = function () { return Math.sqrt(this.x * this.x + this.y *
this.y); };
}
for (var i = 0; i < 10000; i++) {
new Point(0.0, 0.0).length();
}
