Subject: Initialize a subclass inside a namespace

I have a namespace Foo and a class Bas and a class Bar. I am adding
classes Bas & Bar are both inside the namespace Foo.

module Foo
  class Bas
  .
  end

  class Bar
  .
  end
end

I have some dynamically added classes that are subclasses of Bar, but I
want them to be in a namespace under Foo::Bas e.g. Foo::Bas::ThisClass
& Foo::Bar::ThatClass

class this < Bar
 .
end

I put them into the namespace Foo::Bas as follows;

module Foo
  class Bas
    def self.load_stuff
       module_eval File.read(file_name_where_this_class_is_defined)
    end
  end
end

This all works, but I would like to include some code that runs in the
context of ThisClass but before the contents of
file_name_where_this_class_is_defined, but the catch is I cannot assume
the names of the classes being loaded from the file, therefore I am
looking for a callback that is run in context of ThisClass as soon as
ThisClass is defined.

Any ideas?

Thanks,
James
