Is it possible to specify formatting options for to_yaml in ruby?

Question

The code

require \'yaml\'
puts YAML.load(\"
is_something:
  values: [\'yes\', \'no\']
\").to_yaml

produces

--- 
is_somethin

This ugly hack seems to do the trick...

class Array
  def to_yaml_style
    :inline
  end
end

Browsing through ruby's source, I can't find any options I could pass to achieve the same. Default options are described in the lib/yaml/constants.rb.
