debug.rb

def debug(msg, object)
  print "# [debug] #{msg} "
  begin
    Marshal::dump(object)
    raise if object.nil?
    puts h(object.to_yaml)
  rescue Exception => e  # errors from Marshal or YAML
    # Object couldn't be dumped, perhaps because of singleton methods -- this is the fallback
    puts "--- #{object.inspect}"
  end
end
