Up to and including Julia 1.0, the language is very much in a “can do” design phase: we’re focused on allowing people to do difficult things, not preventing them from doing stupid things. It turns out that high-productivity, high-performance numerical computing is a gold mine for problems that have not been well addressed by traditional computer science programming language designs. Once we’ve satisfactorily allowed people to do all the things we want to, we can start thinking about features that prevent people from doing things.
