Rails spinoffs - Jan 2007 - bind() vs bindAsEventListener()

Can anyone tell me what the difference is between these two protoype
methods?

Is bindAsEventListener just used to be compatible with IE''s Event
model?

I''m thinking the only difference between the 2 methods is that
bindAsEventListener passes the event into the function.

I want to know how I can practically apply these.

METHODS COPIED FROM prototype-1.5.0_rc1.js:

Function.prototype.bind = function() {
  var __method = this, args = $A(arguments), object = args.shift();
  return function() {
    return __method.apply(object, args.concat($A(arguments)));
  }

}

Function.prototype.bindAsEventListener = function(object) {
  var __method = this, args = $A(arguments), object = args.shift();
  return function(event) {
    return __method.apply(object, [( event ||
window.event)].concat(args).concat($A(arguments)));
  }

bindAsEventListener guarantees that your handler is both bound to the
proper "this" reference, and passed the event object as its first
argument.  bind only does the former: your first argument would get lost...
