I can barely read most of your blog posts, for instance. Daniel's comment on your latest entry was more approachable, though vague. From what I understand, a monad is a function that returns (result or side-effect) instead of just a result. The analogy I use is a Java method where the return value also incorporates all exceptions that CAN be thrown from the method (or parameters), whether they were actually thrown or not. This implies correlation between knowledge of monads and the shift to using unchecked exceptions in Java although I'm unable to articulate exactly why. I guess that's just my level of understanding; I get why things are neat, am uncertain on the application, and unable to grasp the wider implications.

I guess that’s just my level of understanding; I get why things are neat, am uncertain on the application, and unable to grasp the wider implications.

Are there specific areas you need help with? Trent, have you tried to understand what a monad is? Are there specific areas you need help with?

$A(ul.getElementsByTagName('input')).map(Element.extend).findAll(function(input) {return input.type == 'radio';}).each(function(radio) {
radio.disable();
radio.checked = false;
});

Yes, that’s javascript.
