Idiomatic Go Tricks
summary
Shows concrete Go patterns and copyable snippets: uses line of sight code layout and consistent defer usage for deterministic cleanup, demonstrates teardown-as-return where setup returns a cleanup function to be deferred (useful in tests), provides a startTimer that captures time and returns a stop closure used with defer, implements optional validation via type assertions, uses single-method interfaces and HandlerFunc in place of structs, offers a retry helper (attempts < 5 example) and a semaphore built from a buffered channel to limit concurrency (example: five goroutines).
