| // 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. |
