Yes, that sort of thing is easily caught by strict type checks. They’re also able to catch things that are sometimes okay for weak hints, sometimes not. For example, some *but not all* strings are accepted for integer and float parameters, and some *but not all* floats are accepted for integer parameters. Strict checks make this much simpler and not dependant on the value: either some type is accepted, or it isn’t. Because of that, strict types can actually be effectively analysed ahead-of-time by static analysers, IDEs and so on, and so you can catch some types of errors while editing your code, without even needing to run it. This is quite a powerful feature. Nikita might have more to say on that.
