   No, I do NOT want garbage collection.  Since GC cannot handle the
   problems of circular-list garbage without outrageous time expenditures,
   and for all the other reasons you mentioned above, GC is NOT desirable.
   Furthermore, GC encourages sloppy programming.  I'd be very happy to see
   GC explicitly PROHIBITED.
