I wrote an awesome node.js module for use at StackVM - a module called node-lazy that does lazy list processing through events!

It comes really handy when you need to treat a stream of events like a list. The best use case currently is returning a lazy list from an asynchronous function, and having data pumped into it via events. In asynchronous programming you can't just return a regular list because you don't yet have data for it. The usual solution so far has been to provide a callback that gets called when the data is available. But doing it this way you lose the power of chaining functions and creating pipes, which leads to not that nice interfaces. (See the 2nd example below to see how it improved the interface in one of my modules.)
