here is my point though:

=============
module test;

import std.stdio, std.file, std.json;

void main()
{
     string myFile= "source.json"; // a file produced by: dmd -o- 
-X source.d

     string js = readText(myFile);

     JSONValue j = parseJSON( js[1..$-1] ); // why do I have to do 
this??

     writefln("%s = %s", j["kind"].str, j["name"].str);
     writefln("file = %s", j["file"].str);

}
