I typically find it easier to use a registration process, e.g.

in mod1.rb:

class X
  def self.identify; "foo"; end
end

::MODULES << X

in mod2.rb:

class Y
  def self.idenfity; "bar"; end
end

::MODULES << Y

main.rb:

require 'set'
MODULES = Set.new

Dir["*.rb"].each {|f| load(f)}

MODULES.each do |mod|
  mod.identify
end

Cheers
