features:
- - System for dynamically registering types
- - Support for single-inheritance of types
- - Multiple inheritance of stateless interfaces

Methods

-A <emphasis>method</emphasis> is a function within the namespace scope of
+A *method* is a function within the namespace scope of
a class. It usually operates on the object instance by passing it as a
strongly-typed first argument.
If it does not operate on an object instance, it is dubbed
-<emphasis>class method</emphasis>.
+*class method*.
Methods cannot be overloaded. That is, the #ObjectClass and method name
uniquely identity the function to be called; the signature does not vary
except for trailing varargs.
-Methods are always <emphasis>virtual</emphasis>. Overriding a method in
+Methods are always *virtual*. Overriding a method in
#TypeInfo.class_init of a subclass leads to any user of the class obtained
via OBJECT_GET_CLASS() accessing the overridden function.
The original function is not automatically invoked. It is the responsibility
