FWIW, I've come up with something that looks like:
--8<---------------cut here---------------start------------->8---
(use-modules (ice-9 pretty-print))
(define (print-hash-map h)
(map (lambda (x)
(newline)
(display (car x))
(display ":\n")
(map (lambda (x)
(format #t "~a:\n" (car x))
(pretty-print (hash-map->list cons (cdr x)))
(newline))
(hash-map->list cons (cdr x)))
(newline))
h))
(print-hash-map (hash-map->list cons (dataset-csv-reader "rand.csv")))
--8<---------------cut here---------------end--------------->8---
I think the above is clanky as I already know the
structure of my hashmap before-hand.
