  		// summary:
  		//		Monitor nodes in this NodeList for [bubbled] events on nodes that match selector.
  		//		Calls fn(evt) for those events, where (inside of fn()), this == the node
  		//		that matches the selector.
  		// description:
  		//		Sets up event handlers that can catch events on any subnodes matching a given selector,
  		//		including nodes created after delegate() has been called.
  		//
  		//		This allows an app to setup a single event handler on a high level node, rather than many
  		//		event handlers on subnodes. For example, one onclick handler for a Tree widget, rather than separate
  		//		handlers for each node in the tree.
  		//		Since setting up many event handlers is expensive, this can increase performance.
  		//
  		//		Note that delegate() will not work for events that don't bubble, like focus.
  		//		onmouseenter/onmouseleave also don't currently work.
  		// selector:
  		//		CSS selector valid to `dojo.query`, like ".foo" or "div > span".  The
  		//		selector is relative to the nodes in this NodeList, not the document root.
  		//		For example myNodeList.delegate("> a", "onclick", ...) will catch events on
  		//		anchor nodes which are (immediate) children of the nodes in myNodeList.
  		// eventName:
  		//		Standard event name used as an argument to `dojo.connect`, like "onclick".
  		// fn:
  		//		Callback function passed the event object, and where this == the node that matches the selector.
  		//		That means that for example, after setting up a handler via
  		//			 dojo.query("body").delegate("fieldset", "onclick", ...)
  		//		clicking on a fieldset or *any nodes inside of a fieldset* will be reported
  		//		as a click on the fieldset itself.
  		// example:
  		//	|	dojo.query("navbar").delegate("a", "onclick", function(evt){
  		//	|			console.log("user clicked anchor ", this.node);
  		//	|	});
  
  		// Possible future tasks:
  		//	- change signature of callback to be fn(node, evt), and then have scope argument
  		//		to delegate(selector, eventName, scope, fn)?
  		//	- support non-bubbling events like focus
  		//	- support onmouseenter/onmouseleave
  		// 	- maybe should return an array of connect handles instead, to allow undelegate()?
  		//	- single node version
  
  		return this.connect(eventName, function(evt){
  			var closest = dojo.query(evt.target).closest(selector, this);
  			if(closest.length){
  				fn.call(closest[0], evt);
  			}
  		}); //dojo.NodeList
  	}
