Playing with go1.18beta1 generics on Advent of Code
I've been doing similar (in three langs, though Ive fallen behind on go and rust over the past few days) -- https://github.com/A-UNDERSCORE-D/aoc2021/blob/main/aoc/go/util/slice.go is most of my generic go fun, lots of implementations of higher order functions and nice wrappers

As usual, first implementation. Actually started by doing sum(range(1, steps+1)), and after solving remembered that theres a math thing for that (sum(0..n) = n * (n + 1) / 2). Nothing super fancy other than that. Code Finally starting to see speedup from pypy. That JIT is amazing but has its costs.

https://github.com/A-UNDERSCORE-D/aoc2021/blob/main/aoc/go/six/06.go -- Nothing super fancy. Nice ability to pick arrays over slices here though. Probably contributes a bit of speedup.
