Right now I don't remember such code. Just to refresh my memory,
please provide a link.

How about:
\version "2.19.36"
#(define-markup-command
(page-range-fromproperty layout props page-ranges symbol)
(list? symbol?)
(define (my-nmbrs rngs)
(append-map (lambda (e) (iota (- (last e) (- (car e) 1)) (car e) 1)) rngs))
(let ((m (chain-assoc-get symbol props))
(page-nmbr (chain-assoc-get 'page:page-number props -1)))
(if (markup? m)
;; prevent infinite loops by clearing the interpreted property:
(interpret-markup
layout
(cons
(list (cons symbol `(,property-recursive-markup ,symbol)))
props)
(if (and (string? m)
(number? (string->number m))
(= (string->number m) page-nmbr))
(format #f "~a"
(let ((my-ranges (my-nmbrs page-ranges)))
;; if entries from `page-ranges' are done, fall back to
;; usual page-numbering
(if (> (length my-ranges) (1- page-nmbr))

page-nmbr)))
m))
empty-stencil)))
#(define ranges '((1 24) (52 64) (70 80) (100 110)))
