ちなみにこれのRuby元コードはどこにあるかというとrack/rack/lib/rack/utils.rbにあります。

HTTP_STATUS_CODES = {
  100 => 'Continue',
  101 => 'Switching Protocols',

  507 => 'Insufficient Storage',
  508 => 'Loop Detected',
  510 => 'Not Extended',
  511 => 'Network Authentication Required'
}

これをシンボル化してるのが下記。

SYMBOL_TO_STATUS_CODE = Hash[*HTTP_STATUS_CODES.map { |code, message|
  [message.downcase.gsub(/\s|-|'/, '_').to_sym, code]
}.flatten]
