Fourteen Years of Go — Russ recaps a productive year for Go that included the introduction of profile-guided optimization (PGO), enhanced coverage profiles to improve testing, better toolchain management, the first generic standard libs, slog, and more. Here’s hoping the next year is just as great.

Go's 1.22+ ServeMux vs Chi Router — One of Go’s most interesting active proposals this year has been around enhancing the built-in HTTP router – now likely to land in Go 1.22 or later. Folks are starting to weigh up whether to use it or stick to existing options – Jon plans to try it in new projects, but stay with Chi or gorilla/mux where they're already in place.

'Ungrammar' in Go and Resilient Parsing — You’ve probably heard of abstract syntax trees (ASTs) but concrete syntax trees (CSTs) are also a thing and directly reflect the syntax of the input language. Ungrammar is a DSL for defining CSTs that’s used in Rust, but Eli has re-implemented it in Go.
