Simplicity is the ultimate sophistication. – Leonardo Da Vinci

You can use it within any framework or standalone, as a micro-framework:

composer require leocavalcante/siler

use Siler\Functional as λ; // Just to be cool, don't use non-ASCII identifiers ;)
use Siler\Route;

Route\get('/', λ\puts('Hello World'));

This outputs "Hello World" when the file is reached via HTTP using the GET method and an URI path that matches "/". Got the idea, right?
