This allows us to get rid of some of the validation in sanity_checks() as mypy handles this validation at "build time", and any typos in the enum instantiation would be a runtime error rather than a silent failure. Additionally, it allows us to encode some of the behaviour of the different output types into the type definition itself by using methods.
