If you need to test again nil "every third function or method", then that reflects broken abstractions and/or very dated Ruby. For "maybe nil" situations, modern Ruby code will lean heavily into safe navigation, dig, or wrapping values, and sometimes monads or similar. If that's not enough for you, Ruby has optional type checkers available.
