An object used to set up special properties. Each key on attr.special is a name of a property/attribute that has special behaviors when being get, set, or bound to.

`Object`

attr.special.foo = {
    get: function(){
        return this.foo;
    },
    set: function(val){
        this.foo = val;
    },
    addEventListener: function(){
        // Listen to this property changing some how
    }
};
