Author here. Please note that the "cheap" in the title refers to the effort needed as well as how sophisticated the tricks are; benchmarking and optimizing your algorithms is still super important! This was discussed quite a bit on the Rust subreddit [1] when it was published.

Perhaps "low cost" in the title would have made it clearer since "cheap" as a word has a lot of connotations.

Language can be very hard to get right and I have struggled with this a lot personally.

I prefer low effort.
