I can't support this proposal. Adds more syntax to a language that is
already becoming cramped. I also don't see the purpose of having
simple constructors like this? Are you going to add (n choose k)
simple constructors to a class? I could get behind field initializer
syntax ala C# "with" modeling the syntax we have for structures.
new Person() {name: "Bob"};
