Oh, vastly complicate my code, so that I can do something equivalent to what I get in a few lines. Please reconsider further coding suggestions.

I gave this suggestion before looking at how you were using it, either of my other suggestions would trivial within your current code. Note that your current solution relies on the user (or another program running a diff) to compare for a specific instance where as this allows the running code to check in a self-contained way. I'm not saying one is better than the other here, just that there are merits to both.
