Dear Kirk, I tried this too, but disassembling to code reveals that the foreach generates extra
instructions when compared to this (dmd 1.00 linux):

 void bar(A...)(A a) {
      static if (a.length>0) foo();
      static if (a.length>1) foo();
      static if (a.length>2) foo();
      static if (a.length>3) foo();
      ...
 }

I tried this without any optimizations. I just want to be sure that the compiler guarantees the
behaviour at compile time. This function is time critical.
