Subject: a most undangerous Hash#store!

Hi--

Think I need a better name for this method. It is anything but
dangerous. Any ideas?

  # As with #store but adds the key/value pair
  # only if the key isn't already in the hash.

  def store!(key, value)
    unless key?(key)
      store(key,value)
      return value
    end
  end
