— Every data structure you add in any area can affect type safety in some way
The idea that it could somehow slowdown dev, just as being a minor property of the source code you'd write anyways, is not really valid
— Give an example where type system is useful and no user input
— Compile time type checking
— User input validation is not exactly type safety
— Type safe code is just not able to perform actions on an objects which would not work on the object
— It literally could not do so because of the way the code would have to be designed, it's not run-time type checking
— Iterators are a great example of type safety in practice, because they standardize a data structure's serialization, meaning the code which prefers to rely on iterators is "more" type safe
— People at my workplace say that adding something i.e type safety to current workflow and adopting to that will slow it down
— And in a way it is thinking over something that i rather not have without considering type safety so there is some cost of time
— Now how much it would be and the will benifits outweigh the cost that i don't know yet
— Where is the time cost?
