Jquery also references "this" inside the function as the object / element
clicked..

Subject: Re: [Proto-Scripty] Binding functions to $$ directly
jQuery conflates the meaning of $ and $$ in a useful manner, but
Prototype provides the invoke function to shortcut what you are doing
here.
$$('#div1 p span.someclassName').invoke('observe','click', function(el)
{
alert('b');
});
To my mind, it's a little less magic and a lot more intentional. Note
also in this case that where you have el, the reference is really to the
click event, so I would write this as function(evt) just to note that.
Prototype also scopes 'this' inside of your looped function, so if you
wanted to alert(this), you would get the individual span element as your
value.

How come I got to this
$$('#div1 p span.someclassName').each(function(el)
{
Event.observe(el, 'click', function(event)
{
alert('a');
});
});
instead of something like this ?
$$('#div1 p span.someclassName').observe('click', function(el)
{
alert('b');
});
Any way to get the latter to work like in jQuery ?
