Fargo: a Scheme for Node.js? Node.js supports only one language!
The guys who developed Node.js implemented it on top of a virtual machine which supports only one programming language - JavaScript. If they'd wanted us to use multiple programming languages they could have implemented Node.js on top of the Java/Hotspot VM and it's rich and mature support for multiple languages. But they didn't. There are a couple examples of "other" languages being used to write Node.js programs, such as CoffeeScript.
