signalling callbacks). So I do this:

list.Sort((x, y) => x - y);

Beware of overflow: this is not a good comparison function. E.g. see:

using System;
class App
{
static void Main()
{
int a = int.MaxValue - 3;
int b = int.MinValue + 3; // so a > b, right?
Console.WriteLine("a = {0}, b = {1}, a > b = {2}", a, b, a > b);
Console.WriteLine(a - b); // so this is positive, right?
// a - b = -7 => oops!
}
}

stream.BeginRead(
buffer,
offset,
count,
delegate(IAsyncResult ar)
{
...
},
null);

This manual continuation-passing style cries out for a machine
translation. I've still got this one on my todo list...
