> TODO[3 years ago] The thing is, you might also be not reading that piece of code for the sake of performance optimization. In this case such TODO is a testimony of premature optimization being evil: like, the code has obviously been fine for at least three years without any smartypants optimization that the developer at that time envisioned to become necessary. Though yeah, it could have equally been just a 3-year-old ticket in the issue tracker. However, you won't learn about it when casually exploring the code.
