Go

Write simple, explicit, readable Go. The language rewards clarity over cleverness.

"Simple" means obvious, not minimal — standard idioms (defer f.Close(), %w-wrapped errors, immediate if err != nil checks) ARE the clarity, not cleverness. Never strip a required idiom in the name of simplicity.
