#define MRB_MT_REMOVED_P
        

  

    
"removed" tombstone: MRB_MT_FUNC flag set with NULL function pointer.
This combination never occurs naturally (C functions are never NULL).
Unlike undef (proc=NULL without MRB_MT_FUNC), a removed marker makes
mt_get() return 0 ("not found"), blocking ROM chain walk while
allowing superclass lookup.
