D - Abstraction for primitive types?

Something that would allow to write generic interfaces like

   TypeToUnistring(type t) {
      TypeInfo *pti=t.info;
      char buf[40];
      int n=(*pti.toMem)(&t,buf);       
      return MemRetUnistring(buf,n);
   }

or

   void ArrayRandomize(type [] ar) {
      ....
      algorithm using swap from typeinfo
      ....
   }

?

What means "now"? In the next version DMD 0.62?
