In July, it [became a proposal](https://github.com/golang/go/issues/61410), and now Eli Bendersky gives a practical example of what the new multiplexer can offer and compares it against `gorilla/mux`. Hacker News hosted [an extensive discussion](https://news.ycombinator.com/item?id=37898999) too, with debate over the pros and cons of having a panic occur when multiple routes match and the use of magic strings vs. verb-specific methods. Go 1.22 is expected in early 2024, so expect to see more on this topic before then.
