> There was a PR to improve the performance of `Integer#succ` in early 2024, which helped me understand why anyone would ever use it: “We use `Integer#succ` when we rewrite loop methods in Ruby (e.g. `Integer#times` and `Array#each`) because `opt_succ (i = i.succ)` is faster to dispatch on the interpreter than `putobject 1; opt_plus (i += 1)`.” I find myself using `#succ` most often for readability reasons, not just for performance. Here's an example where I use it twice in my UUID library's `#bytes` method to keep my brain in “bit slicing mode” when reading the code. I need to loop 16 times (`0xF.succ`) and then within that loop divide things by 256 (`0xFF.succ`): https://github.com/okeeblow/DistorteD/blob/ba48d10/Globe%20Glitter/lib/globeglitter/inner_spirit.rb#L215-L229 https://github.com/okeeblow/DistorteD/blob/ba48d10/Globe%20G...
