Rails spinoffs - Sep 2007 - Prototype - Convert list menu options into an enumerable?

I have a simple question and I can''t find an answer for! Driving me
nuts.

I have a select list:

<select name=''lista'' id=''lista''
size=''5''>
<option value=''1''>1</option>
<option value=''2''>2</option>
<option value=''3''>3</option>
</select>

I want to iterate through all the options in the select. Now, I can do
a generic for loop but that''s no fun.

When I try:

$(''lista'').options.each()

I get an error about each() not being a function even though $
(''lista'').options is an array.

Can I convert it to an enumerable object somehow?

"options" is not an Array, but a built-in object.  Use $A() to  
perform the conversion.

$A($(''lista'').options).each(function (v) {console.log(v);});
