(Vimscript) Stack Overflow Question

I do not know whether Vimscript is a popular topic over on Stack Overflow, but this question was asked in July and has apparently received no answers; perhaps SO users here could look at it:

Iterating over a string in Vimscript or Parse a JSON file
http://stackoverflow.com/q/17751186/758011?sem=2

**Note that there is a bounty of 300 reputation on it now (for a week), and also that answers might be better given over there than as a reply to this, as that way they make it to SO as an answer to that question** (and of course SO reputation, in case that's of interest, can't be awarded by means of email). :)

Thanks!
