mixin assembler does not work?

I'd like to write that more like this:


enum Vala(uint count, alias arr) = format("
     asm {
         sub ESP, %%(count);              // Reserve 'count' bytes
         mov %%(arr.stringof), %%(count); // Set a.length = 'count'
         mov %%(arr.stringof) + 4, ESP;   // Set &a[0] to reserved 
bytes
     }");
