JSONValue only works with the build in types, not with user 
defined types. Either you define a specific function for the 
class that returns a JSONValue. Easiest way to do that would be 
to build an associative array with strings as keys with the 
names, and JSONValues as values and turn that into JSONValue, 
i.e. (untested):
class MyClass
{
        string[] _data;
        alias _data this;
        // ...
   JSONValue toJSON()
  {
    JSONValue[string] aa;
    JSONValue[] dataJSON = _data.map!((a) => 
JSONValue(a)).array;
    aa["data"] = JSONValue(dataJSON);
    return JSONValue(aa);
  }
}

isnt alias this supposed to do this implicitly?

convert this
auto jsValue = JSONValue(new MyClass());

into this
auto jsValue = JSONValue((new MyClass())._data);
