class Hash
  # Merges the caller into +other_hash+. For example,
  #
  #   options = options.reverse_merge(:size => 25, :velocity => 10)
  #
  # is equivalent to
  #
  #   options = {:size => 25, :velocity => 10}.merge(options)
  #
  # This is particularly useful for initializing an options hash
  # with default values.
