Re: `new Foo` vs `new Foo()`

If we apply the same rule as for methods, you should not add parens unless
your constructor is side-effecting (which is probably not a great idea in
itself).
That's the reasoning for case classes, I guess, since a side-effect-free
case class should be a case object.

I tend to leave off the empty parens. Their presence should imply potential
side-effects.
