I don't know. Procedural code in Golang is pretty trivial - you basic constructs are regular in the selection, iteration, and sequence sense with a sprinkle of interfaces and some CSP constructs for concurrent design. That covers like 99% of what you need to write good code. I'd say pattern matching is pretty helpful Ala ML, Haskell, Rust. Beyond that all the GOF and Solid and all that jazz seems to do way more harm than good IMHO.

If you have ever looked at the code of the most successful programs the code is anything but "good". Have you glanced at the Linux Kernel code lately? But again, "good" is very subjective. The Linux Kernel works well enough to server the purpose of millions of users and enough people understand it. Its good code!
