Hmm, but the '@@' is optional, as I can leave it off and still get the
contents.html view if there is no object named contents.html in that folder.
This would seem to confuse developers, as if there IS an accidental
collision of an item name with a view that is unknown to the developer, it
will return the view out of nowhere.
Shouldn't the '@@' should be *required* on views to avoid this ambiguity?
