 	<p>Objects have a hierarchy, in which objects can descend from others, hence inheriting all the properties defined in their <a href="#n1.3.7.6">owner</a>. This enables great flexibility and modularization of the code.</p>
 	<p>Objects can be set to be of a certain type, placing an object type immediately after the at sign, or automatically deriving it from the context. It is followed by whitespace, and optionally an object name and more optional whitespace, followed by a block. Inside the block, its properties are defined.</p>
