Thanks, Paul. Unfortunately it doesn't seem to work for me:

class Bar
end

class Foo < Bar
end

Object.class_eval do
   remove_const :Foo
   const_set :Foo, Class.new(Bar) { }
end
GC.start

class Foo < Bar
end

ObjectSpace.each_object(Class) do |klass|
    puts klass if Bar > klass
end


It still prints out both Foo classes in this case. Any ideas?
