Subject: method_missing - but can it be "isolated" to per-project basis?

Hi.

I have been playing with the following code (explanation follows after
the code):

------------------------------

  require 'pp'

  class Object
    def method_missing(*args)
      return args.join ' '
    end
  end

  def foo(i = nil)
    puts i if i
    puts yield if block_given?
  end


  foo
  foo 'testing 1'
  foo { 'testing 2' }
  foo { testing 3 }

  # The code above returns:
  #   testing 1
  #   testing 2
  #   testing 3

------------------------------

Ok, this code defines method foo, and we use 4 different ways to
call it.

What I was most interested in was the last version - I want to access
all what was passed in a block as string. This is useful for one
project, but it is not good to modify Object in such a way in larger
projects.

Any advice on whether it is possible to keep this piece of code only on
a per-project basis? Like, I want to extend class Object only in the
context of that specific object, but if I use it in a larger project, I
don't want to use that very modification to class Object (because,
outside that project, it would be counter-productive to act on
method_missing that way).
