I'm also somewhat concerned about conflating instantiation and method calls — although they both ultimately call a method, they're not actually the same thing, since instantiating an object does extra work at the same time. Being able to just look for "new" in code is helpful. Open to being convinced otherwise (examples from other languages would be helpful), but my initial reaction isn't really positive. Thanks, Adam
