Yeah my thinking here is to find some problem that involves some usage of a list of words or any other basic string building task. For example, you are assembling the "ingredients" of a "recipe". I think if you gave it the specific context of "hey this seems to be malicious, why?" it might figure that out, but I think if you just point it at the code and ask it "what is this?" it will get tricked and think it's a basic recipe function.

Based on the complete out of my behind number I'd say something like 99.9999% of successful hacks I read about use one level of abstraction or less. Heavy emphasis on the less.

So I think one layer of abstraction will get you pretty far with most targets.
