Thanks a lot for the migraine... I guess...  :)

But, yes, it's beginning to work with self.inherited, which gives the
most elegant solution IMHO :

test.rb :

#! /usr/local/bin/ruby

class Test
  class <<self
    attr_accessor :loaded_classes
    def inherited(c)
      puts "#{c} inherited me !"
      @loaded_classes ||= []
      @loaded_classes << c
    end
  end
end

load "test2.rb"

Test.loaded_classes.each do |c|
  Object.send(:remove_const, c.to_s)
end

load "test2.rb"

test2.rb :

#! /usr/local/bin/ruby

puts "In #{__FILE__}."

class Test2a < Test ; end
class Test2b < Test ; end

ruby test.rb
In ./test2.rb.
Test2a inherited me !
Test2b inherited me !
In ./test2.rb.
Test2a inherited me !
Test2b inherited me !

Yay.

No, I just have to include that in my plugin system to allow for
"hotplugging"...  Hehehehe...
