digitalmars.D - mixin code

I was trying to mixin a class from another file without having to
insert it to the compile line, so this is what i did:


//file args.d
//this is what i would like to mixin
////////////////////////////////////////////
module args;

template args()
{

    class Arguments
    {
         this(TypeInfo[] inf, void* argptr)
         {
              typeinfos = inf;
              pointers.length = inf.length;
              pointers[0] = argptr;
              for(int i=1; i<inf.length; i++)
              {
                   pointers[i] = pointers[i-1] + inf[i-1].tsize;
              }
         }
         int length(){return typeinfos.length;}
         TypeInfo type(int i){return typeinfos[i];}
         void* value(int i){return pointers[i];}
         private
         {
              TypeInfo[] typeinfos;
              void*[] pointers;
         }
    }
}
/////////////////////////////////////////////////

//the file where it is mixed to:
//testvarargs.d
////////////////////////////////////////////
import std.stream;

import args;
mixin args.args!();

void func(...)
{
     Arguments arg = new Arguments(_arguments,_argptr);
     stdout.printf("Funkcija func pozvana s %d argumenata",arg.length);
     for(int i=0; i<arg.length; i++)
     {
          if(arg.type(i) == typeid(float))
          {
           //stdout.printf("%d
          }
     }
}

int main ( char [] [] args )
{
 func(100,3.141);
 getch();
 return 1;
}

This works (even though i had some unreproducable linking errors)
but it gets more complicated if in args.d the template is called the same as
class,
and i have a feeling something like template modules was mentioned in this
NG
some time ago, but does it still exist? Is it documented anywhere?

I think it went something like:
//a.d
module a(T);

//b.d
import a!(int);

?

This would be a good way to import templated code, but does it exist or not?

No, sorry.

That's ok, it isn't that important to me now, i only asked because i thought i read something about something like that.
