Also Perl6.  A wide variety of languages and formats, from Make to
MIME, use the colon-suffix notation.  It's very natural, as it matches
the original English meaning of the colon.  The SMTP library in the
Hato mail server let's you easily send mail like so:

  (send-mail From:    "Dr. Watson <guest at grimpen.moor>"
             To:      "Sherlock Homes <not-really at 221B-baker.street>"
             Subject: "First Report"
             Charset: "ISO-8859-1"
             Body:    "Moor is gloomy. Heard strange noise, attached."
             Attachments: '((File: "howl.ogg")))
