I just double-checked, and see that you are right and I was wrong. I
just grabbed a listing of some Modula-2 code, and looked at it for
BEGIN...END pairs; and when I saw them used in procedure declarations,
I stopped looking at the rest of the code. Bad Neel. :)

Here's a sample for people who wonder what I'm talking about:

PROCEDURE UnifyArgs(list1, list2: TypeList);
  BEGIN
    IF (list1 = Empty) AND (list2 = Empty) THEN 
      RETURN; 
    END;
    IF (list1 = Empty) OR (list2 = Empty) THEN
      ErrorMod.Msg("Type clash");
    ELSE
      UnifyType(list1^.head, list2^.head);
      UnifyType(list1^.tail, list2^.tail);
    END;
  END UnifyArgs;
