Node.js `require` into an array instead of a variable
<p>It is possible to <code>var x = require('x.js')</code> and use <code>x</code> later on to access all the nice stuff. What is the closest way to build an array of required things, like:</p>

<pre><code>var xs = [require('a.js'), require('b.js')]
</code></pre>

<p>and then access the exported features as <code>xs[0].feature</code> and <code>xs[1].feature</code>?</p>
