react-css-modules-example.js

function cssmodularize(strings) {
   /* TODO: Un-stub */
  return {
    '.foo': 'Button-foo-abcd'
  }
}

class Button {
  
  static styles = cssmodularize`
    .foo { /* ... */ }
  `
  
  render() {
    const s = this.constructor.styles
    console.log(s)
    // ...
  }
}

const button = new Button()
button.render()

Why is this awesome? Separation of concerns. Everything concerning a button is in the one file. Syntax highlighting might be a bitch, but that can come later (hey, it happened for JSX).
