;: function. The variable *CALLER* will be bound to the calling QQuickItem,

;;
;; Possible integers encoded as hex strings in JS (see function HEX above)
;; are automatically converted back to integers.

;; Strings starting with ':' are assumed to be Lisp keywords, if composed by
;; alphanumeric characters, and if they have a following argument.
