Code that you insert on this page could contain malicious content capable of compromising your account. If you import a script from another page with "importScript", "mw.loader.load", "iusc", or "lusc", take note that this causes you to dynamically load a remote script, which could be changed by others. Editors are responsible for all edits and actions they perform, including by scripts. User scripts are not centrally supported and may malfunction or become inoperable due to software changes. A guide to help you find broken scripts is available. If you are unsure whether code you are adding to this page is safe, you can ask at the appropriate village pump.

	// ve.InstanceList class, which has add and remove methods and
	// emits add and remove events. Then replace ve.instances and
	// ve.init.target with instances of ve.InstanceList, and make all
	// callers use add/remove instead of push/splice. Then just
	// connect to ve.instances or ve.init.targets and listen for
	// add/remove events. That's the way I recommend doing it."
