Xavier, I don't know why you want to have an anonymous module with a
local constant, but if you really need this and are willing to change
the public interface a little bit you could do

  m = Module.new
  m.module_eval do
    # methods for dependent classes
    def depend(file)
      puts "#{self} depends on #{file}"
    end
    # methods to define a dependent class
    def self.const_missing(name)
      const_set(name, Class.new)
    end
    def self.dependent_class(cls, &blk)
      parent_module = self
      cls.class_eval do extend(parent_module) end
      cls.class_eval(&blk)
    end
    # public interface for dependent classes
    dependent_class self::A do
      depend("afile.rb")
    end
  end
