+// GTMLightweightProxy
+//
+// An object which does nothing but stand in for another object and forward
+// messages (other than basic NSObject messages) to it, suitable for breaking
+// retain cycles. It does *not* retain the represented object, so the
+// represented object must be set to nil when that object is deallocated.
+//
+// Messages sent to a GTMLightweightProxy with no represented object set will
+// be silently discarded.
