Seems to me like the last thing you want to do is worry whether the LLM has a large enough context window to keep an eye on all duplicates. So I'd argue to deduplicate directly, where possible.
"karate chop flashlight" love this description! That's exactly why I've stayed with Motorola after my G5 just got too slow. I'm now on a Moto G Pro from 09/2020, it's getting fairly slow but all in all it gets the job done.
This. I have argued with plenty of developers on why comments are useful, and the counter arguments are always the same.
I believe it boils down to a lack of foresight. At some point in time, someone is going to revisit your code, and even just a small `// Sorry this is awful, we have to X but this was difficult because of Y` will go a long way.
While I (try to) have very fluid opinions in all aspects of programming, the usefulness of comments is not something I (think!) I'll ever budge on. :)
And in a few million years, the next intelligent life form will examine remains of human texts, and wonder: with all the tools and knowledge they possessed, how could they not have prevented their demise?
