Hmm, I was thinking of

  temp = load("find.rb", true)
  temp::Find.find(...)

but unfortunately load returns true, not the module object :-(

Here's a messy way:

  require 'find'  # the _old_ implementation of find

  #require 'new_find'  # contains the following:
  module NewStuff
  module Find
    def self.find
      puts "hello"
    end
  end
  end

  # Main program
  old_find = Find rescue nil
  begin
    Find = NewStuff::Find
    Find.find  # this is the code to be executed
  ensure
    Find = old_find
  end

  Find.find(".") { |f| puts f }

?
