Subject: YAML.load and exception objects

I found a problem about YAML.load() and exception objects.

% ruby -v -ryaml -e "YAML.load(Exception.new.to_yaml)"
ruby 1.8.2 (2004-06-19) [i386-cygwin]
/usr/local/lib/ruby/1.8/yaml/rubytypes.rb:274:in `object_maker': wrong
number of arguments (3 for 2) (ArgumentError)
         from /usr/local/lib/ruby/1.8/yaml/rubytypes.rb:274
         from /usr/local/lib/ruby/1.8/yaml/rubytypes.rb:272:in `call'
         from -e:1:in `transfer'
         from /usr/local/lib/ruby/1.8/yaml.rb:119:in `load'
         from /usr/local/lib/ruby/1.8/yaml.rb:119:in `load'
         from -e:1

I think so that the latest YAML.object_maker() in lib/yaml.rb was changed.

  YAML.add_ruby_type( /^exception/ ) { |type, val|
      type, obj_class = YAML.read_type_class( type, Exception )
