I have a design decision hanging on if issue 3073 is valid:

http://d.puremagic.com/issues/show_bug.cgi?id=3072

I'm not looking to get it fixed right now (I wouldn't mind if it was :) but 
to move forward on something I need to know if it ever will be.

The short version is should this work:

template Do(T...)
{
  void It()
  {
      foreach(i,_;T) writef("%sn", T[i]);
  }
}

struct S
{
    int i; int j; float k; char[] m;
    mixin Do!(i, k, m);
}
