Subject: Help optimizing

I'm going to cross-post this from the Rails group, because some of the
people here are Ruby ninjas and don't read that forum, and I'd like help
getting this function optimized... its results are useful in a Rails
perspective, but it's functionality has nothing to do with Rails at all.

class Hash
  def to_params(parent = '')
    ret = ''
    self.keys.each do |key|
      if self[key].is_a? Hash
        if parent == ''
          ret += self[key].to_uri(key.to_s)
        else
          ret += self[key].to_uri(parent + "[#{key.to_s}]")
        end
      else
        if parent == ''
          ret += "#{key}=#{self[key]}&"
        else
          ret += "#{parent}[#{key}]=#{self[key]}&"
        end
      end
    end
    return ret.chomp('&')
  end
end

Anybody got any optimizations(either quicker speed, or less text and
comparable speed) for that one?

Thanks.
