basically i want
fwrite("1 ","2\t","3\n");
to print
/*7*/ 1 2    3

do I have to iterate through _argptr

I think so. Also noting that C-style varargs can only work with 
fundamental types (Am I correct there? I am carrying this assumption 
from C++.), you may be happier with a template-parameter solution:

import std.stdio;

File f;

static this() {
     f = File("hello_world.txt", "w");
}


//f is a File*
void fwrite(int line = __LINE__, Args...)(Args args)
{
         f.write("/*",line,"*/ ");
         f.write(args);
}

void main() {
     fwrite("1 ","2\t","3\n");
}

The template works great.
Thanks!
