/// ### What it does
///
/// Forbid Webpack loader syntax in imports.
///
/// ### Why is this bad?
///
/// This loader syntax is non-standard, so it couples the code to Webpack. The recommended way to
/// specify Webpack loader configuration is in a [Webpack configuration file](https://webpack.js.org/concepts/loaders/#configuration).
///
/// ### Example
/// ```javascript
/// import myModule from 'my-loader!my-module';
/// import theme from 'style!css!./theme.css';
///
/// var myModule = require('my-loader!./my-module');
/// var theme = require('style!css!./theme.css');
/// ```
