Proposal: Don't Add Generics to Go's Core Libraries in 1.18 — Rob is suggesting that new versions of the core libraries be placed in the experimental namespace so folks can test them before core gets ‘genericized’. The idea is that while we get generics in 1.18, we can take more time to figure out how the core libraries will use them.

'Hey Linker, Can You Spare a Meg?' — Tailscale, a mesh VPN service, has its core code written in Go, but on iOS their network extension is limited to a mere 15MB of memory. Ensuring they stayed within this limit involved the Tailscale engineers digging deep into Go’s runtime, garbage collector, and more, ultimately resulting in improvements for all Go users coming to Go 1.18.

Safer Enums in Go — For those of us that give more than an iota about enums, this post is a nice exploration of ways to make them better (integers bad, strings good) but certainly not perfect.

GoPlus (Go+): A More Scripty Variant of Go — It’s not going to win any awards for having a good, non-confusing name, but the overall idea of having a Go compatible language that leans more towards Python-style simplicity for scripting and data science use cases is interesting nonetheless.

truthy: Truthy Condition Testing with Go Generics — While this is “a little bit of a joke package”, it’s still something we should start to see once 1.18 is out.
