digitalmars.D.learn - static switch

Does a switch statement acting on a template parameter act just 
like a chain of  static if-else's? That is, does it just generate 
the code for the matching case?

enum E { A, B, C }

class Blah(E param) {
   void foo() {
     switch(param) {
       case(E.A) : blah;
       case(E.B) : ....
       default:
     }
   }
}

Thanks,

It doesn't. It's easy to check anyway.

Not for me :) I just saw that it worked, and wondered if it 
worked statically.
Thanks!
