and if player_name_list happens to be {"fribble","sinJin","Sinjin"},
you lose.

Try
  @program foo_utils:member
  elt = args[1];
  lst = args[2];
  j = 0;
  while ( (i=elt in lst) && strcmp(elt, lst[i]) != 0)
    j = j + i;
    lst[1..i]={};
  endwhile
  return i ? j + i | 0;

On second thought, just upgrade.  :-)

Random style peeve #227:

  !strcmp(x,y)

is something that will get you shot in certain parts of the world
(Hint: are we comparing for x == y or x != y?  Hard to tell, no?)

  strcmp(x,y) == 0

uses exactly the same number of ticks and has the advantage of
looking a lot more like an equality test (which it is)
