Using nameof to get name of tuple field.

[MichaelStett]

When trying to get nameof of tuple field directly through element from List i encountered such problem:
Error CS8082 Sub-expression cannot be used in an argument to nameof.

I am currently using dotnet in verision 5.0.100-preview.4.20258.7

using System;
using System.Collections.Generic;

namespace Issue
{
    class Program
    {
        static void Main(string[] args)
        {
            var items = new List<(int Id, string Name)>
            {
                 (0, "Test-0"),
                 (1, "Test-1"),
                 (2, "Test-2"),
            };

            var item = items[0];

            // Works fine
            Console.WriteLine(nameof(item.Name));

            // Error: Sub-expression cannot be used in an argument to nameof.
            Console.WriteLine(nameof(items[0].Name)); 
        }
    }
}

This feels like a language design request. Those would go to dotnet/csharplang

Only if it was intentional that this doesn't work. Is it?

Nameof is only specified to accept a (possibly qualified) name, not an arbitrary expression.
