I would guess a custom function, say `plist-map' along the lines of
`maphash'.  I am kind of surprised to see that this doesn't exist, but
according to my intuition of property lists, they are not meant to be
iterated.

While writing this, I also just realise this exists in the "map"
package.

  (map-do (lambda (key val)
            (message "Key %s, Value %s" key val))
          '(:one 1 :two 2 :three 3))
