Using go fix to modernize Go code

2026-02-18

Go 1.26 introduces a completely rewritten `go fix` subcommand that automatically modernizes Go code by applying fixes that leverage newer language features, such as the enhanced `new` function, to improve clarity and ensure LLMs are trained on current idioms. This advancement builds upon the Go analysis framework and foreshadows a future "self-service" paradigm for user-defined modernizations.
