Enumerates the items in the input ReadOnlySpan<T> instance, as pairs of value/index values.
This extension should be used directly within a foreach loop:
ReadOnlySpan<string> words = new[] { "Hello", ", ", "world", "!" };
foreach (var item in words.Enumerate())
{
// Access the index and value of each item here...
int index = item.Index;
string value = item.Value;
}
The compiler will take care of properly setting up the foreach loop with the type returned from this method.
