## This whole list bit seems a bit pointless right now, why not just create and array ref and assign the one json object? |
20
|
|
|
|
|
|
|
## The plan is to allow different data_key for each list element, but sensible implementation eludes me at present (IOW, $work doesn't need it) |
21
|
|
|
|
|
|
|
## At least we're not throwing away data if given a list; of course easier solution would have simply been to make an arrayref!! |
