CSS Modules: Extract Imports

Transforms:

:local(.continueButton) {
  composes: button from "library/button.css";
  color: green;
}

into:

:import("library/button.css") {
  button: __tmp_487387465fczSDGHSABb;
}
:local(.continueButton) {
  composes: __tmp_487387465fczSDGHSABb;
  color: green;
}

Specification

An extend-import has the following format:

composes: className [... className] from "path/to/file.css";
