Subject: [ruby-talk:24024] How do I dynamically add functions to an object?

Hi:

I am trying to add functions to an object. The code is in
a protected environment and each object has a string that
defines new code. I would like to put the code in a unique
module but don't know if this is possible. Here is what I
have so far.

s =<<EOM
module UniqModule
  def a()
    puts "in a"
  end
end
EOM

class SomeClass
end

c = SomeClass.new
#eval s
#c.extend("UniqModule");c.a    #=> wrong argument type String (expected
Module)

#c.extend(UniqModule);c.a      #=> in a
This last line works, but it would force me to have a fixed
module name.

Thanks
