Maybe a more useful resolution to this would be to state that while all code is data, no data should be code?

You could, if you were crazy enough, write perfectly valid JSON that passed the values to eval() or a parser or what have you. And while there are encodings in JSON that don't work in javascript (i've broken JS innumerable times trying to get that to work) JS does of course allow you to add closures as an object, or an array, whatever you like, and some forms of valid JSON (if not all) are also valid javascript. So you could indeed use JSON to compute things if you wanted to.
