Do you grok C# 2.0?

I run into a couple of great questions in .Net 2.0 today, which influenced some of the things that I did there. I'm wonderring how many others would spot them. Without compiling the code, what is the result of the following code snippet?

using System;
using System.Collections.Generic;
public class Sample<T> where T:class
{
 private static string typeName = typeof(T).FullName;
 
 public string TypeName
 {
  get { return typeName; }
 }
 
 
 public List<Printer> PrintNumbers()
 {
  string [] names = { "Ayende", "Rahien", "Foo", "Bar" };
  List<Printer> list = new List<Printer> ();
  foreach(string s in names)
  {
   list.Add( delegate(){ Console.WriteLine(s); } );
  }
  return list;
 }
}
public delegate void Printer();
public class Start
{
 public static void Main()
 {
  Console.WriteLine(new Sample<Type>().TypeName);
  Console.WriteLine(new Sample<string>().TypeName);
  foreach(Printer print in new Sample<Start>().PrintNumbers())
  {
   print();
  }
 }
}

Hint: In my project, I took advantage of the first and had to work around the second.

Th answers will be posted tomorrow.
