Yes, but apparently D's default precision for output is less than F#'s 
so how about the following? :p

     "%(%.15g\n%)".writefln(iota(0, PI/2, PI/2/9).map!sin);

Just for demonstration, I would not write anything like that but the 
following is fine because now the format becomes the second parameter: :)

     iota(0, PI/2, PI/2/9).map!sin.writeF("%(%.15g\n%)");

void writeF(R)(R range, string format)
{
     return writefln(format, range);
}
