 			Every value in Gravity is an object, and every object is an instance of a class. Classes define an object's behavior and state. Behavior is defined by methods which live in the class. Every object of the same class supports the same methods. State is defined in fields, whose values are stored in each instance.<br><br>Like <a href="functions.html">functions</a> a <strong>Class is a first class object</strong>, that means that it can be stored in local variables (even in <a href="list.html">Lists</a> or <a href="map.html">Maps</a>), passed as a function parameter or returned by a function.

 	}
 			</code></pre>
-			
+
 			<h4 class="section-h4">Class methods and properties</h4>
 			<p>A class method (or property) is a method (or property) that operates on class objects rather than instances of the class. In Gravity you can specify a class method (or property) using the static keyword:</p>
 			<pre><code class="swift">

 				When I started developing the Gravity programming language I knew nothing about how to develop an interpreter or how to traverse an AST. This project proved to be an invaluable experience to me and I am sure that developing a programming language from scratch is the best way to become a much better developer with a deeper understanding about what happens inside the compiler we use every single day.<br><br>
 				I'd like to collect all my experience in this book, trying to not assume any prior knowledge except the C language. This book guides you to gain the foundational knowledge required to write a new programming language from scratch and will give you concrete answers to questions like what is really a closure or how a garbage collector works under the hood.<br><br></p>

 	Practically any good multiplier works. I think you're worrying about
 	the fact that 31c + d doesn't cover any reasonable range of hash values
