Ruby on Rails

When you're in a program with all static function definitions and invocations the source of truth is the functions that are right there. You can't change those without losing Type safety, whereas you can change a runtime system Lose type safety, but not know it not know yet because and that's where the lie comes in So I almost feel like lie is like lies like a really strong word. It does not give you the same kind of safety that you would get if you were working with a source definition that was local and therefore Was always a fire plan.
