I work on an alternative Ruby implementation, and it looks like I'll be able to take these type definitions and use them to add extra type constraints to my intermediate representation very easily - just insert a type constraining node around each expression that's annotated with a type. It'll remove extra guards and increase performance, so should definitely be an option.
