Project mention: Scientist: A Ruby library for carefully refactoring critical paths | news.ycombinator.com | 2023-11-14

I wrote one (https://github.com/boxed/scientist) as I found the existing ones very complicated and that just gives me a bad feeling. Since I'm the author of mutmut (https://github.com/boxed/mutmut), I also made sure my implementation was 100% mutation tested before I used it in production.

I used my implementation to replace number parsing in my work project: https://kodare.net/2021/04/04/safe_number_parsing.html
