`using` in JavaScript

Posted at 2013-11-21

Dirty. Names are assigned directly into GLOBAL. It breaks file scope.

main.js

using = require('using').using
using(require('foo'))
console.log(new Foo) #=> { name: 'Foo' }
require('bar')

using.js

exports.using = function (mod) {
    for (var name in mod)
        GLOBAL[name] = mod[name]
}

foo.js

exports.Foo = function () {
    this.name = 'Foo'
}

bar.js

console.log(new Foo) #=> { name: 'Foo' }

There may be another way but I can't find it...
