I think you hit on the core of the issue: LiveCode Script does not
(yet) support true lists.
xTalks have traditionally approached that with strings, as you noted,
and with the efficiency and ease of chunk expressions that's not a bad
way to handle things.
But it becomes problematic when trying to move data between systems
using a data structure like JSON designed specifically for JavaScript.
I believe LiveCode Builder supports true lists.
It would be nice of some of the language features in LC Builder that are
also common in other languages could be migrated into LC Script as well.
As an interim workaround, I suppose you could write your own
LCArrayToJSON function that handles the specific use cases you're
looking for, but that's tedious and would need to be written and used
carefully with specific tasks in mind.
