Examples

// YUI
YUI.add([identifier], function(Y){
            
    // Export Y.foobar
    Y.foobar = "YUI!";
    
    // Export Y.baz as a concatenation of two imported values
    Y.baz = Y.fizz + Y.buzz;
    
}, [version,] [config/dependencies] );


// AMD
define([name,] ["dependencyA", "dependencyB"], function(dependencyA, dependencyB){

    // Always returns an object
    return {…};

});


// CommonJS Modules/1.1 + Wrapper
define(function(require, exports, module) {
    //Require is passed in as a local
    var someModule = require("someModule");

    // Exports is what you hang values/functions off of, similar to Y.
    exports.baz = someModule.bop;
    exports.fizzbuzz = function() {
        ...
    }
});


// CommonJS Modules/2.0
module.declare([identifier,] function(require, exports, module) {
    exports.hello = function() {
        return "Hello World"; 
    }
});

YUI Plugin for RequireJS

There are a few issues, but seems to work reasonably well and is a nice proof of concept. I'll ask if he is actually using this in a live application. https://github.com/WilcoFiers/UseYUI-for-RequireJS
