SIMD intrinsics and the possibility of a standard library solution

Most of the time is spent parsing, but this problem lends itself nicely to a SIMD formulation, which using vectorclass doesn't even require detailed knowledge of the intrinsics. Hot runs take ~14 µs on a Core i9-12900K, including I/O. Full code is (here)[https://github.com/ahans/aoc2022/blob/main/cpp/day04.cc], the interesting part is this, where we process 32 elements at once:
- Significantly faster quicksort using SIMD
- Parsing JSON faster with Intel AVX-512
- What do you think is faster for batch-processing a lot of "double-type" arithmetic?

[2021] [Nim] Nim is Beautiful + All days in < 130ms
This year I was writing two sets of solutions in Nim. The first one focuses on idiomatic, nice and short and readable Nim. The other focuses purely on speed. The combined running times of the fast solutions is 130 ms. Please let me know if you have any tips on how to make my solutions more simple and/or idiomatic.

Beautiful Nim! My solution is actually very similar.
