I beg to differ; you need not require() before using autoload():

  sun@yantram ~/tmp> cat nfc.rb
  NFC = Class.new do
    require 'singleton'
    include Singleton

    def find(*args)
      p :find => args
    end
  end.instance

  p :loaded_nfc


  sun@yantram ~/tmp> cat run_this.rb
  autoload :NFC, 'nfc'
  NFC.find('123')


  sun@yantram ~/tmp> multiruby run_this.rb

  VERSION = 1.8.7-p72
  CMD     = ~/.multiruby/install/1.8.7-p72/bin/ruby run_this.rb

  :loaded_nfc

Why would you need two files?  Because NFC is a gem?

Since RubyGems overrides Kernel#require() and Kernel#autoload() uses 
Kernel#require(), the autoload approach should work even if loading NFC 
from a gem.
