I forgot to mention;

(use-modules (uuid)
             (rnrs bytevectors))

(display
 (make-version-3-uuid
  (u8-list->bytevector
   ;; URL namespace UUID is 6ba7b811-9dad-11d1-80b4-00c04fd430c8
   '(#x6b #xa7 #xb8 #x11 #x9d #xad #x11 #xd1 #x80 #xb4
          #x00 #xc0 #x4f #xd4 #x30 #xc8))
  "https://example.org"))
(newline)

yields the same result as Python’s

import uuid
uuid.uuid3(uuid.NAMESPACE_URL, 'https://example.org')
