The following program fails to compile, complaining that there is no ToString()
method that takes zero arguments.   This is distilled from a larger program:

using System;
using System.Collections.Generic;

public abstract class AnyObjectId : IComparable<ObjectId>, IComparable
{
        public override string ToString()
        {
                return "Foo";
        }
}

public class ObjectId : AnyObjectId
{
        public static string ToString (ObjectId i)
        {
                return i != null ? i.ToString() : "Foo";
        }
}

The compiler reports:

ObjectId.cs(16): error CS1501: No overload for method `ToString' takes `0'
arguments
