Can I output strings using core.stdc.stdio?

Yep that's the best thing I can do! Code:

import core.stdc.stdio : printf;
import std.string : toStringz;

void put(A...)(string prompt, A args) {
     for (ulong i = 0; i < args.length; i++) {
         if (typeof(args[i]).stringof == "string")
             printf("%s\n", args[i].toStringz);
     }
}

void main() {
     string h = "World!";
     string w = "World!";
     put(h, w);
}

I'm getting two errors. First that i can't be read at compile 
time and second that I don't initialize the function right. So I 
know I'm doing something wrong but I don't know why... Any ideas?
