/* Assume that this component exists somewhere: */
twttr.klass('twttr.components.Person', function(name, location) {
  this.name = name;
  this.location = location;
});

/* A few ideas for asyncronous instantiation: */

//  1. Pass variable number of constructor arguments and callback as the last argument
var callback = function(instance) {
  console.log('Now I have an instance:', instance);
};
twttr.new('twttr.components.Person', name, location, callback);

//  2. Pass constructor arguments as an array and then a callback
twttr.new('twttr.components.Person', [name, location], callback);

//  3. Callback passed to .ready event
twttr.new('twttr.components.Person', name, location).ready(callback);
