What you want is an associative array:

char[char[]] myMap;

myMap["one"] = "first";
myMap["two"] = "second";
myMap["three"] = "third";

http://www.digitalmars.com/d/arrays.html#associative

Traversal is also very easy with this type:

foreach(key,value; myMap){
   writefln("%s => %s",key,value);
}

Tests are done with the 'in' operator:

if("two" in myMap){
   writefln("mymap contains a value for 'two'");
}
