On page 205 of "The C++ programming language" by Stroustrup, there is 
listing of a get function for circular list class slist.

ent slist::get()
{
   if (last == 0) slist_handler("get from empty slist");
   slink* f = last->next;
   ent r = f->e;
   last = (f==last) ? 0 : f->next;
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   delete f;
   return r;
}

The line starting with "last = ...." seems to be wrong.  The function
get is suppose to return and remove the head of the list.
Can anyone confirm this ?
