It works already (un?)fortunately:

     auto test = AliasSeq!("The product of %s and %s is %s", 2, 5, 
10);
     writeln(test);  //Prints "The product of %s and %s is %s2510"
     writefln(test); //Print   "The product of 2 and 5 is 10"

This DIP is just taking that 1 extra small step to allow i"" 
strings to be lowered to tuple literals.
