Question about foreach extension resolution for arrays.

[En3Tho]

Please tell me if this code can work? I did another extension method ToIndexable() to make this kind of thing work.

     public record struct ArrayIndexedEnumerator<T>(T[] array) : IEnumerator<(int, T)>
    {
        private int _index = -1;
        public bool MoveNext()
        {
            _index++;
            return _index < array.Length;
        }

        public void Reset()
        {
            _index = -1;
        }

        public (int, T) Current => (_index, array[_index]);

        object IEnumerator.Current => Current;

        public void Dispose()
        {
        }
    }

    public static ArrayIndexedEnumerator<T> GetEnumerator<T>(this T[] array) => new(array);

    static void Test()
    {
        foreach ((int, int) xx in new[] { 1, 2, 3 }) // Error -> Cannot convert element type 'int' to iterator type '(int, int)`
        {
            
        }

        foreach (var (idx, elem) in new[] { 1, 2, 3 }) // No 'Deconstruct' method with 2 out parameters found for type 'int'
        {
            
        }
    }

context:

<div class="py-8 flex flex-col gap-4">
            @foreach (var (currentIndex, title) in new[] // <---
            {
                "Less than $25k", "$25k to 100$k", "$100k to $300k", "$300k to $500k", "$500k to $1M", "$1M or more"
            }.ToIndexable()) // <---
            {
                <label>
                    <input type="radio" class="peer absolute w-0 h-0" @onclick="() => selected = currentIndex"/>
                    <div class="flex px-4 py-8 h-12 items-center justify-between shadow-sm cursor-pointer rounded-md bg-gray-300">
                        <span class="ml-3 font-medium text-xl">@title</span>
                        <span class="mr-3 h-6 w-6 rounded-[50%] bg-white border-solid border border-black
                                     @If(selected == currentIndex, "border-blue-700 border-[4px]")"></span>
                    </div>
                </label>
            }
        </div>

The extension method is the suggested route.
