-// This visitor checks that a finalizer method does not have invalid access to
-// fields that are potentially finalized. A potentially finalized field is
-// either a Member, a heap-allocated collection or an off-heap collection that
-// contains Members.  Invalid uses are currently identified as passing the field
-// as the argument of a procedure call or using the -> or [] operators on it.
