One nice thing about using a bare 'puts' in your code is that you can 
override it as your code matures.

  def puts(msg)
    @log.info(msg)
  end

Anyway, even Kernel can be overridden/deleted.  A similar hack can be 
seen in Derby, where you swap YAML into DRb:

  require 'drb/drb'
  require 'yaml'

  module DRb
    Marshal = ::YAML
  end
