comment #2. 

window.onerror sucks. JScript thinks it's an Event. Poor API design copied
during browser wars. 

Should we copy this legacy approach?

Event onerror callback signature should be single argument: an object. 

This could be either of type: either Error or ErrorEvent.

Example:

errorCaught = function errorCaught( ev ) {
  var stack = ev.stack;
  log( stack );
  ev.preventDefault();
};

window.addEventListener( "error", errorCaught, false );
