  26 --     CHECK THAT A LOOP PARAMETER HIDES AN OUTER DECLARATION OF A
  27 --     HOMOGRAPH. ALSO CHECK THAT THE OUTER DECLARATION IS DIRECTLY
  28 --     VISIBLE IN BOTH DECLARATIVE REGIONS BEFORE THE DECLARATION OF
  29 --     THE INNER HOMOGRAPH AND THE OUTER DECLARATION IS VISIBLE BY
  30 --     SELECTION AFTER THE INNER HOMOGRAPH DECLARATION.
