It's strongly typed, but it's also duck typed. Also, in ruby everything is an object, even the class itself, so type checking there is weird. Sure it stops you from running into "'1' + 2" issues, but won't stop you from yeeting VeryRawUnvalidatedResponseThatMightNotBeAuthorized to a function that takes TotalValidatedRequestCanUseDownstream. You won't even notice an issue until: - you manually validate - you call a method that is unavailable on the wrong object.
