Ruby

Hi all:
Now I have problem about dynamiclly inheriting form a class.
For example:

class_name=‘MyClass’
klass = Object.const_set(class_name, Class.new)
klass.class_eval do
…
end

now i get a class named 'MyClass',then i want the MyClass inherit

from another
class ‘AnotherClass’,how can I do it?

class MySuperClass; end

Class.new(MySuperClass) #=> create anonymous class that inherits from
MySuperClass.

Use the optionnal parameter of Class.new:

------------------------------------------------------------- Class::new
Class.new(super_class=Object) => a_class

 Creates a new anonymous (unnamed) class with the given superclass
 (or Object if no parameter is given). You can give a class a name
 by assigning the class object to a constant.
