I wish this is true. But from all the things Swift has supported. It doesn't make compiler or compiler authors happy.

I wish there are more languages that focused on happiness of the compiler authors so that they can write efficient and small compilers with well-thought language features that intentionally limits how much they need to write in the compiler. Today we have such a huge compiler maintenance burden and as a result, you saw inconsistencies everywhere with these languages, and it is after many hundreds of person-year spent.

(Yeah, Go is probably one of the language that focused on compiler authors' happiness)
