// The proper modeling of the domain would be for a Repository to own
// Status. But because some Status methods call Repository methods, I
// have had to make Repository a field in Status instead.(which I've
// marked HACKY in the code below)

// This means that the struct that owns Repository now owns a Status
// and methods in the parent struct call Repository methods look like
// `self.status.repo.some_repository_method()`

// This is my attempt at creating a minimal example(compiling but
// non-functional) of the problem I'm trying to solve. The codebase
// I'm actually working on is here:
// https://github.com/samrat/rug/blob/master/src/repository/status.rs
