Pattern matching can be quite powerful, e.g. in C# (which I wish was more indepth / more featured, it still feels a bit immature :( )

```

    switch(foo)
    {
       case TextBox t:
          Console.Writeline(t.Text);
          break;
       case TextBox when t.Text = "Bob":
          Console.WriteLine("Hello Bob");
          break;
       case Combobox c:
          Console.WriteLine($"{c.SelectedItem}");
          break;
       case null:
          Console.WriteLine("Ooops, null!");
          break;
       case int i when i == 5:
          Console.WriteLine("got an int, and it was 5!");
          break;
       case default:
           // handle the default case.
           break;
     }

```

IN languages like F#, pattern matching can compile time check you have covered all bases as well.

e.g, this won't build

````

    type VariableResult =
      | E of string
      | V of string

    let result = V "variable"

    match result with
      | E e -> printf "was error"

```

As i haven't told it how to handle the V case for that discriminated union. So you get nice compile time checking.

Ugh, how do you format code?

C# doesn't really deserve the name of pattern matching, just a type-based switch (with guards), you can't match on values let alone destructure them.

4 spaces indent.
