Programming in D, page 604 - static foreach fails. Is the code obsolete?

```
import std.stdio;

void main(string[] args)
{
        writeln("args: ", args);
        
        theSwitchStatement:
                switch (args.length)
                {
                        static foreach (i; 1 .. 3)
                        {
                                case i:
                                        writeln(i);
                                        break theSwitchStatement;
                        }

                        default:
                                writeln("default case");
                                break;  // This may also be:  break 
theSwitchStatement;
                }
}
