Everything is a JSONValue. JSONValue has a union inside it that actually

file. (This could be a bit more efficient if I stored obj2, but I think
it's enough to communicate the idea.)
import std.stdio;
import std.json;
import std.file;

void main(string[] args)
{
        auto jsonString = readText("../ml.json");
        JSONValue json = parseJSON(jsonString);
        writeln(json["obj1"]["obj2"]["val1"].integer);
        writeln(json["obj1"]["obj2"]["val2"].str);
        foreach(value; json["obj1"]["val3"].array)
                writeln(value.integer);
}

Output:

1
a string
1
2
3
4

Your question did remind me to document the union members so that the
HTML documentation will show how to access the actual data. I've
uploaded the new version of the file. The link is the same.

Cool.  It looks very simple and easy...just the way I like it.  What you 
have is actually quite nice as I can navigate down to a low-level 
element without having to store 200 different intermediate values. 
Probably not very common, but a nicety for when it's needed.

Thanks!
