Go with mandatory error handling enforced by a linter is probably one of the best ways I've seen reduce mistakes. Not all aspects of the language are perfect, but I'm confident it is loads better than exceptions-based approaches with catch-all exceptions and generic error handling strewn everywhere. I imagine this is especially useful from a banking perspective where mistakes can wipe out millions.
