+Classes are declared using the '''class''' keyword. It may have any of the usual [wiki:AccessModifiers access modifiers]. 
+The Superclass inheritance and Interface conformance are indicated with the '''inherits''' and '''implements''' keywords.
+
+Interfaces are declared in much the same way except the keyword is '''interface''' and method and property bodies are not defined.
+Interface hierarchies (SuperInterfaces) can also be specified using '''inherits'''
+
+Instance variables are declared within the class using keyword '''var'''.
