+1 to adding Iterable<Resource> getChildren() to Resource interface.

...except extending this interface is going to cause some pain for implementors.

How about this..
1) create a ResourceIterableAdapter class which implements Iterable<Resource> - this is used by Java code
2) add a EL function sling:children(resource) which can be used in JSP pages

WDYT?

> When you call Resource.listChildren() or resourceResolver.listChildren() it returns a Iterator<Resource>, this is fine if you want to just iterate through the results using old-style while loops, but if you want to use enhanced loops, you are out of luck.  
> I'm proposing adding an interface to return from these methods which extends both Iterator<Resource> and Iterable<Resource>.  This will allow for using enhanced loops with the results of listChildren().
