Could use a collect equivalent. Maybe also async.

[Insomniak47]

Pirating from the rust stdlib it would be nice to be able to easily aggregate

List<Result<T,TErr>> 
//into
Result<List<T>, TError>;

Maybe look something like:

    public static class CollectExtensions
    {
        public static Result<IEnumerable<TValue>, TError> Collect<TValue,TError>(this IEnumerable<Result<TValue,TError>> results)
        {
            var values = new List<TValue>();
            foreach (var result in results)
            {
                if (result.IsError)
                {
                    return result.Error;
                }
                values.Add(result.Value);
            }

            return values;
        }
    }
