He, is that a challenge? ;-)
Yes. Also known as "bait" ;-)
As I said, my json knowledge is limited to the Wikipedia entry, but
does the
following prototype give a valid json document?
It is. JSON documents normally don't contain newlines. The complexity I
was referring to is linked to the myriad of data types we have in hansl,
each of which requires a different JSON-isation. For example, I would
have stored matrices in a completely different way (that is, vectorisation
+ 2 scalars for dimensions, similar to what we use in mread/mwrite), but
your solution is also nice and has its own advantages.
