They are NSMutableStrings/NSStrings underneath:

irb(main):013:0> "string".class.ancestors
=> [String, NSMutableString, NSString, Comparable, NSObject,
PP::ObjectMixin, Kernel]

And hashes are similarly NSMutableDictionary/NSDictionary:

irb(main):015:0> {}.class.ancestors
=> [Hash, NSMutableDictionary, NSDictionary, Enumerable, NSObject,
PP::ObjectMixin, Kernel]

Couldn't say for sure, but seems like a good move to improve
consistency/compatibility with non-MacRuby code and gems and the like.
