Code inspection: Return value of 'GetEnumerator' method call is never disposed

This inspection reports a generic enumerator that is created but not disposed. Many enumerators implement IDisposable, and skipping disposal can leave resources open longer than intended.

Example

                var enumerator = items.GetEnumerator();
                while (enumerator.MoveNext())
                {
                    Use(enumerator.Current);
                }
            

                using var enumerator = items.GetEnumerator();
                while (enumerator.MoveNext())
                {
                    Use(enumerator.Current);
                }
