Describe the bug

If you use this code:

namespace ConsoleApp41 {
    internal class Program {
        static void Main(string[] args) {
            var Values = new[] {
                ("A", "B", "C"),
                ("A", "B", "C"),
                ("A", "B", "C"),
            };
            foreach (var (A, B, C) in Values) {
                Console.WriteLine(A + C);   
            }

            var D = "";

        }
    }
}

You'll see the following in VS:

D correctly generates CS0219 but B does not.
This makes it easy to miss that B's value is not being used.

Expected behavior

B generates CS0219.

Actual behavior

B does not generate CS0219.

Additional context

I notice that B does generate IDE0059 but D generates both.
