You hate that it takes 2 lines instead of 4 (excluding curly braces) to accomplish the same? The new syntax is not even convoluted, it's pretty intuitive destructuring syntax already available in many modern languages.
In that case, there's absolutely no ambiguity: there's only one `x` you can be talking about.
By the way, value/case classes are such a boon. Very easy to get used to, and once you have, you want to use them everywhere, I guarantee.
