Hopefully you're not relying on NSLog or -description producing reliable
information. It can change at any time, in any OS release. A lot of iOS
developers were caught off-guard when -[NSDate description] changed what
format it used.
If this is just for debugging purposes, you could swizzle -[NSArray
description] and -[NSDictionary description]. Either way, file a bug.
