Rather than doing a `strcmp` here, would it be possible to use one of the methods in `KWObjCUtilities`? I think this should be `KWObjCTypeIsObject`.

Also, if you move this `if` clause into an appropriately named method, such as `+isCopyableForObject:type:`, we could [avoid the comment and make the code cleaner](http://www.informit.com/articles/article.aspx?p=1326509).
