Subject: Inherited & load

Hello.

I've written a mechanism to dynamically load plugins inheriting from a
base class, using the self.inherited method.

Now, in an irb session, I noticed that, even if I (re)load the classes,
the self.inherited is only triggered once.  Short example :

> ruby -v
ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-freebsd6]

> cat first.rb
#! /usr/local/bin/ruby
load "test.rb"
load "test.rb"

> cat test.rb
#! /usr/local/bin/ruby
class Test
  def self.inherited(c)
    puts "#{c} inherited Test !"
  end
end
load "test2.rb"

> cat test2.rb
#! /usr/local/bin/ruby
puts "In #{__FILE__}."
class Test2 < Test ; end

> ruby first.rb
In ./test2.rb.
Test2 inherited Test !
In ./test2.rb.

Is there a trick somewhere that would allow me to trigger the inherited
method at each time the file containing the "sub-class" (e.g. Test2) is
loaded ?

(The real plugin class, if there is a need, is here :
