rueidis
A fast Golang Redis client that supports Client Side Caching, Auto Pipelining, Generics OM, RedisJSON, RedisBloom, RediSearch, etc.
It's important to note that it's possible to use any Redis-compatible client with Valkey. I used the go-redis client, but (at the time of writing) there is work underway to build Valkey specific client libraries. Check the Valkey GitHub org to take look at the forks of existing Redis client libraries such as valkey-go (corresponding to rueidis), iovalkey (corresponding to ioredis), Jackey (corresponding to jedis) etc. These are very early days (at the time of writing), and it will be interesting to see the progress here!

Project mention: Faster interpreters in Go: Catching up with C++ | news.ycombinator.com | 2025-04-05
do a type analysis on each expression you want to "compile" to a closure, and instantiate the correct closure for each type combination.
Here is a pseudocode example, adapted from https://github.com/cosmos72/gomacro/blob/2ff796e3da1057c005c...
/* return a closure that computes x + y when executed /

Not sure how I didn't find this before, but https://github.com/zyedidia/generic looks like a decent library.
Although there are some decent libraries out there for this kind of thing, my complaint mostly stems from the fact that a lot of existing code doesn't involve generics yet.
I think I remember skimming an article about for range loops on Hacker News a while back, but again, my main complaint is still that existing code exists in a way that doesn't incorporate all these new features yet.
