Finding dependencies

[rosszurowski]

We can't detect the dependencies of a given file as of yet. Let's say for instance that we have a setup like the following:

return new Taro()
  .get('styles.css')
  .use(sass)
  .middleware()

How do we know what files styles.scss calls @import on? Is there a cross-language way of figuring this out? Maybe a list of referenced files in a Gulp stream?
