[Proto-Scripty] when to use store

[blechler]

Hi everybody!

Typically when I have an element that I would want to observe I would
do something like:

var myObject = Class.create({
  initialize: function() {
    this.myButton = $('aButton');
    this.addObservers();
  },

  addObservers: function() {
    this.myButton.observer =
this.doSomething.bindAsEventListener(this);
    this.myButton.observe('click', this.myButton.observer);
  },

  doSomething: function() {
    new Effect.BlindDown($('aDivWithContent'));
  }
});

When creating my observer should I be doing something like:

this.myButton.store('observer',
this.doSomething.bindAsEventListener(this));
this.myButton.observe('click', this.myButton.retrieve('observer'));

The method initially presented has worked fine thus far.  Should I be
aware of any caveats?

Thanks!
