I'm going to both agree and disagree. I agree that the specific example of &chown.is_restricted is a bad idea, but only because the POSIX API I was wrapping is itself flawed. In general I would continue to pursue the approach of adding precondition-checks as methods on functions, a concept that is orthogonal to the specific example you are arguing against: I disagree that the code I showed is not simpler that the original S16 approach.
