title: How to get OR permissions instead of AND in REST framework
body: <p>It seems that permission classes are ANDed when REST framework checks permissions. That is every permission class needs to return True for permission to be granted. This makes things like "if you are a superuser, you can access anything, but if you are a regular user you need explicit permissions" a bit hard to implement, you cannot just return False, it will fail the whole stack. Is there a way to maybe short-circuit permissions? Something like "if this permission is granted, stop checking?" or some other way to deal with cases like that?</p>
