I made some changes to

https://github.com/gambiteer/srfi-231/tree/specialized-from-data

that did not include code to implement this suggestion.

I suppose one could do something like

(define (fast-array nested-list interval)
   (list->array (flatten nested-list) interval))

but I don't see how to get around specifying the domain interval.

Or perhaps

(define (nested-list-of-numbers->array nested-list)
   (if (right-shape nested-list)
     (list->array (flatten nested-list) (nested-list->interval
nested-list))))

where nested-list->interval does the obvious thing, but I'm not sure
that this should be in the library.
