   use Atree.Unchecked_Access;
   --  This package is one of the few packages which is allowed to make direct
   --  references to tree nodes (since it is in the business of providing a
   --  higher level of tree access which other clients are expected to use and
   --  which implements checks).

   use Atree_Private_Part;
   --  The only reason that we ask for direct access to the private part of
   --  the tree package is so that we can directly reference the Nkind field
   --  of nodes table entries. We do this since it helps the efficiency of
   --  the Sinfo debugging checks considerably (note that when we are checking
   --  Nkind values, we don't need to check for a valid node reference, because
   --  we will check that anyway when we reference the field).

   --  A short hand abbreviation, useful for the debugging checks
