I like that canBubble and cancelable are now always the last args.

Well, they aren't, strictly; they're after all the required args, since they're
optional, but if a function had other args that could be optional I put those
after canBubble and cancelable. I could change it to make them always the last
args if you think that's cleaner.

+      [bool canBubble = false, bool cancelable = false]) {
+    var e = dom.document.createEvent("BeforeLoadEvent");
+    e.initBeforeLoadEvent(type, canBubble, cancelable, url);
+    return LevelDom.wrapBeforeLoadEvent(e);
   }
+
+  String get url() { return _ptr.url; }
 }
