If you’re familiar with Ruby and Rails, you probably know all about Symbol#to_proc and Methodphitamine. I wanted some similar goodness for Prototype, so I could stop writing


var value = radioGroup.find(function(radio) {
  return radio.checked;
}).value;

var divs = someDivs.findAll(function(div) {
  return div.hasClassName('myClass') 
    && div.visible();
});

and instead write


var value = radioGroup.find('checked').value;

var divs = someDivs.findAll({
  hasClassName: 'myClass', 
  visible: true
});

So I went about writing it. It started off with a simple patch over at Rails Trac that extended the idea behind Enumerable#pluck to lots of other methods, but then I got carried away. You can now use strings, arrays and hashes instead of iterator functions to make your code more readable.
