node.js model setup?

main.js

var task = require('./task');
var t1 = new(task.Task)("Blah");
var t2 = new(task.Task)("Foo");
sys.puts(t1.getBody());
sys.puts(t2.getBody());

var tasks = task.getTasks();
sys.puts(sys.inspect(tasks));

task.js

exports.Task = function(body) {
  this.body = body;
};

exports.Task.prototype.getBody = function() {
  return this.body;
};

// Static fetch function
exports.getTasks = function() {
  var tasks = [];
  tasks.push(new this.Task('getTasks 1'));
  tasks.push(new this.Task('getTasks 2'));
  return tasks;
};
