Hi guys,
is it possible to set hash items at once in hash definition?

;; this works
(define cities:cities)
(cities "ny" "new york")
(cities "sf" "san francisco")
(println (cities "sf"))

;; this not
(define cities:cities '(
    ("ny" "new york")
    ("sf" "san francisco")))

(println (cities "sf"))

Hi,

Try

Code: Select all

(define cities:cities)         ; creates the default functor
(cities '(("ny" "new york") ("sf" "san francisco")))        ; the functor adds the data
(cities)

s.v.

And you can of course combine it into a single phrase like

Code: Select all

((or (define cities:cities) cities)
  '(("ny" "new york")  ("sf" "san francisco")))

but it's not very intelligible.
