-// GPBString is a string subclass that avoids the overhead of initializing
-// a full NSString until it is actually needed. Lots of protocol buffers contain
-// strings, and instantiating all of those strings and having them parsed to
-// verify correctness when the message was being read was expensive, when many
-// of the strings were never being used.
-//
-// Note for future-self. I tried implementing this using a NSProxy.
-// Turned out the performance was horrible in client apps because folks
-// like to use libraries like SBJSON that grab characters one at a time.
-// The proxy overhead was a killer.
