Go if err != nil versus Rust's ? operator
WHAT IT TESTS: judgment on error-handling ergonomics. OUTLINE: Go's explicit checks are verbose but make every error site visible; Rust's ? propagates concisely while still forcing the error into the type, reducing boilerplate.
WHAT IT TESTS: whether you can weigh verbosity against safety in error propagation. ANSWER OUTLINE: Go's if err != nil after each call is explicit and uniform, keeping every failure point visible, but it is verbose and the compiler does not force you to check, so errors can be silently dropped. Rust's ? operator unwraps Ok or returns the Err early (converting via From), giving concise propagation while the Result type still forces you to confront errors; ignoring requires an explicit unwrap, expect, or let _ =.
