New features for those who haven't seen them:

// Primary constructors
public class NamedItem(string name)
{
    public string Name => name;
}

// Default lambda params
var IncrementBy = 
    (int source, int increment = 1) => 
        source + increment;

Console.WriteLine(IncrementBy(5)); // 6
Console.WriteLine(IncrementBy(5, 2)); // 7

// Type aliases
using Point = (int x, int y);

Primary constructors I think are getting a bit too much bloat for the language. I get the purpose and I use them in Scala, but it just feels like too many ways to do a simple thing in C#.

Tuple type aliases FTW

Just still desperately hoping for Union types
