I just want to focus on writing functions. Here's a trivial example.

I would like:

  // math/adder.cs
  public static add(int x, int y) : int {
    return x + y;
  }

Instead of:

  // math/adder.cs
  namespace math {
    class adder {
      public static add(int x, int y) : int {
        return x + y;
      }
    }
  }

Both are callable as:

  math.adder.add(10, 20);
