   * They all follow a similar interface:
   * generator { config-attrs } data
   *
   * `config-attrs` are “holes” in the generators
   * with sensible default implementations that
   * can be overwritten. The default implementations
   * are mostly generators themselves, called with
   * their respective default values; they can be reused.
   *
   * Tests can be found in ./tests.nix
   * Documentation in the manual, #sec-generators
