A recent version of Chrome Blink enhanced windonw.onerror to provide a real Error object with column numbers as well, so you no longer need to wrap all entries into JS with a uncaughtexception handler, which is what Closure, GWT, Dart, Angular, et al do. Combined with sourcemaps, you can get perfect deobfuscated stack traces with little overhead.
