 * TObjective-C.h is for supporting coexistence of both the ARC (Automatic 
 * Reference Counting) mode and the Non-ARC mode of Objective-C 
 * in the same source code.

 *
 * Before:
 *
 *    var = [aObject retain];
 *    [aObject release];
 *    [aObject autorelease];
 *    [super dealloc];
 *    CFFunction(obj);
 *
 * ARC and Non-ARC compatible:
 *
 *    #import "TObjective-C.h"
 *    var = [aObject retain_stub];
 *    [aObject release_stub];
 *    [aObject autorelease_stub];
 *    [super dealloc_stub];
 *    CFFunction(bridge_stub obj);
 *
 *    Don't use retain_stub for @property(retain).
 *    Use NSAutoreleasePool like this:
 *        #if __has_feature(objc_arc)
 *          @autoreleasepool {
 *              // code 
 *          }
 *        #else
 *          NSAutoReleasePool *pool = [[NSAutoReleasePool alloc] init...
 *          // code
 *          [pool release];
 *        #endif
