Accessing just the value of an object but not the attributes

I see the role of as.vector(). But even if as.vector() needs to keep its attribute-dropping side-effect for compatibility reasons, wouldn't a dropattr() still be a good idea?
Not needed, as attributes(x) <- NULL removes all attributes. I have no idea why this might be useful to you .. remember that class and dim are attributes, for example. Because they are not normally visible, assignment functions like attributes<- are too little appreciated in S programming.
For instance, I can assign attributes to closures, but wont get rid of them using as.vector() - and neither using as.function() by the way ... So if I dont know in advance what kind of object it is and I do want to just access the "value" in any case I have to check the type ... ?
