Представьте что у вас есть некий класс API, который вы хотите использовать. Но вместо того чтобы всегда и везде писать api.method(args) вы хотите просто писать use_dsl { method(args) } внутри вашего обьекта.

client = Client.new(ThirdPartyAPI.new)

client.run_local_variable
# Output:

    this._currentTasks = 0;
    this._queue = [];
  }

  start(task) {
