I think stud number 7 was onto something. How about this:

CommonDef = %q{
  def self.hello
    puts "hello from #{self}"
  end
}

module A
  module_eval CommonDef
end

module B
  module_eval CommonDef
end

A.hello
B.hello

module B
  def self.hello
    puts "different hello"
  end
end

A.hello
B.hello

===>

hello from A
hello from B
hello from A
different hello

_______

Seems to work right.

best,
Dan
