I just noticed in D1 that the values for the cases in a switch must be

that changed before the book? It's a real PITA for dynamic code.

I actually tested this. I was surprised. In D2, variables are allowed...

But not dynamic ones

It is a surprise though.

What do you mean 'dynamic ones' ?
Eg, this works:

  for (int i=0; i<10; ++i) {
    switch(x) {
    case 3:
         break;
    case i:
         break;
    default:
    }
  }
