         All of the array accesses that are identified as being able to be
         scalarized will be transformed by this transformation.
 
         An array access will be scalarized if:
         1. All accesses to the array use the same indexing statement.
         2. All References contained in the indexing statement are not modified
-           inside of the loop (loop variables are ok).

         3. The array symbol is either not accessed again or is written to
-           as its next access. If the next access is inside a conditional
-           that is not an ancestor of the input loop, then PSyclone will
