C# Brainteaser print

Here's some code using the anonymous method feature of C# 2. What does it do?

using System;
using System.Collections.Generic;

class Test
{
delegate void Printer();

static void Main()
{
List printers = new List();
for (int i=0; i < 10; i++)
{
printers.Add(delegate { Console.WriteLine(i); });
}

foreach (Printer printer in printers)
{
printer();
}
}
}

Answer: Ah, the joys of captured variables. There's only one i variable here, and its value changes on each iteration of the loop. The anonymous methods capture the variable itself rather than its value at the point of creation - so the result is 10 printed ten times!
