   In mutable Settings, these return the same object with a var set.

   In mutable Settings, these return the same object with a var set. In immutable, of course they will return a new object, which means we can't use "this.type", at least not in a non-casty manner, which is unfortunate because we lose type information without it.

   ...but now they're this.type because of scala/bug#3462. The immutable side doesn't exist yet anyway.
