--- title: "Keeping generics away from the core libraries.. for a while." publication: "Go Weekly" issue: 383 published_at: "2021-10-15" canonical_url: "https://golangweekly.com/issues/383" --- Plus how an optimization by Tailscale improved Go's linker for all of us, and an Elm-inspired TUI framework. | #​383 — October 15, 2021 [Unsubscribe](https://golangweekly.com/leave/*|UID|*)|[Read on the Web](https://golangweekly.com/issues/383) Go Weekly [![\](https://res.cloudinary.com/cpress/image/upload/w_1280,e_sharpen:60/qfbscdxnuhnuqoakr2f5.jpg)](https://github.com/golang/go/issues/48918) [Proposal: _Don't_ Add Generics to Go's Core Libraries in 1.18](https://github.com/golang/go/issues/48918) — 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. Rob Pike "How to use these ideas in the standard library requires great thought and planning. Putting them in the library now also adds a significant burden to rolling out the release. I propose that we do not update the libraries in 1.18." ___ Rob Pike ['Hey Linker, Can You Spare a Meg?'](https://tailscale.com/blog/go-linker/) — 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.
