Tricky Code

Without running the code, what is the result of this masterpiece?
class Program { static void Main(string[] args) { DoSomething("a","b"); } public static void DoSomething<T>(IList<T> set) { Console.WriteLine(set.Count); } public static void DoSomething<T>(params T[] items) { List<T> set = new List<T>(); foreach (T t in items) { if (t == null) continue; set.Add(t); } DoSomething(set); } }
It surprised the hell out of me until I figured out what was going on, then I was very amused. This code works exactly as it should be, to produce a very different result than the expected one.
