Writing directly to properties like that makes no sense in a language that has class-private properties and internal constructors. It's fine in Rust or Go that don't have internal constructors, but it's just not a good fit in a PHP-like language. And new Foo(a: 'A", b: 'B") is already perfectly readable and self-documenting. Yet another constructor-invoke syntax on top of that would offer nothing. --Larry Garfield
