Feature Request: SCENE_FUNC macro

We have a CREATE_FUNC macro, which allows us to call the create() function of a class without implementing this function - as long as we add CREATE_FUNC( myclass ) to the header file.

It seems like a good idea to also have a SCENE_FUNC macro, since this would spare us from having to put a scene() function into every CCLayer derived class that we are writing.

Example (based on CREATE_FUNC):

/**
 * define a scene function for a specific type, such as CCLayer
 * @__TYPE__ class type to add scene(), such as CCLayer
 */
#define SCENE_FUNC(__TYPE__) \
static CCScene* scene( void ) \
{ \
    CCScene* pScene = CCScene::create(); \
    __TYPE__ *pRet = new __TYPE__(); \
    if( pRet && pRet->init() ) \
    { \
        pRet->autorelease(); \
        pScene->addChild( pRet ); \
        return pScene; \
    } \
    else \
    { \
        delete pRet; \
        pRet = NULL; \
        return NULL; \
    } \
}

What do you think about this idea?
