In this context, it is not an operator and so there is no method associated with its use in this context. Gary Wright

If you want to find out if somebody is inheriting your class, implement 'MyClass.inherited' (it's a hook). -- Posted via http://www.ruby-forum.com/.

The '<' in a class definition is not an operator and so doesn't have an associated method. It looks like an operator but is not parsed or interpreted as an operator when used in a class definition.
