try something like this:

class Stone

end

class Wall
    def initialize
        brick = Class.new Stone
        self.class.const_set :Brick, brick
    end
end

puts 'before initialize'
p Wall.constants
p Wall::Brick.ancestors rescue nil

puts 'after initialize'
Wall.new
p Wall.constants
p Wall::Brick.ancestors
