I asked here:
*[Does Node.js require inheritance?](https://stackoverflow.com/questions/5348685/node-js-require-inheritance)*

And I was told that I can set variables to the global scope by leaving out the variable.

This does not work for me.

That is, the following does not make the `_` available on required files.

```
_ = require('underscore');

```

I can set with Express.js's `app.set` and have it available elsewhere though.

Is that how this is supposed to work?
