Go Weekly

Go 1.18 Beta 1 is Available (with Generics) — It’s here! It’s here! Just in time for the holidays! The preview release of Go 1.18 with generics (and a few other very nice new features) is ready for you to play with (and test). The final release isn’t due until 2022 so there’s plenty of time. See the draft release notes for more.

• 📗 Powerful Command-Line Applications in Go by Ricardo Gerardi has been published by Pragmatic Bookshelf.

• Mat Ryer of the Go Time podcast ▶️ asked the Go team lots of questions about lots of things from garbage collection and generics to Go 2 and how community surveys influence their work.

• The Gorilla Toolkit (perhaps best known for the mux router) is looking for new maintainers.

Replacing interface {} with any — Don’t worry about this syntactic sugar until you’re working on Go 1.18, but it’s a type alias to be aware of and might save a little typing time in future ;-)
