Only until you've figured it out, at which point you're god. You could make it non-repeatable somehow to avoid that, but magic is depicted as being mainly old, repeated spells most of the time, like in the comic. You could also move to something like Brainfuck or even Malbolge where coding a single new program is hard. As I learned the hard way, though, you're still going to have no control over what ends up being easy and what's not.

Actually, it's more like homeomorphic encryption since you have a system of some bounded complexity instead of a single fixed piece of information. That's usually harder, but then again you actually want the scheme to be "insecure" in this case.
