   the halting *function* is an abstract mathematical object that maps a   
   machine description to whether the machine described halts or not, not   
   the associated machine description that attempts to compute this

   u can argue about what computing machines actually exist all u want, and   
   whether anything actually computes the halting *function*, i'm not going   
   to argue over what the halting *function* itself is
