I think that would depend on the type system. Dart has an optional type system (no types, some types, strong mode) with different levels of safety. Interestingly though, even if you write strong mode code, the types are completely thrown out before execution. It's a bit of an aside, but I don't know (libs aside) why anyone would choose python over dart. Types are great for large projects, but tend to add verbosity and development time for small scripts (thus why there are so few strongly typed scripting languages). SML/ocaml show that there is a nice middle ground where most types are inferred, so you can keep your types without too much work. Unfortunately, they've been around for decades with little usage in the profession.
