No, it is basic. If you have a sum type, and you have no defined behaviour for one of the terms of the sum type, your code is not type-safe and a language that aspires to "basic type safety stuff" should at least issue some kind of error about it. In a putatively statically-typed language (ie one that does type checking at compile time), you'd expect that error to happen at compile time. |
