To be clear, you actually could reuse the switch keyword for an expression:

    $x = switch ($y) {/* ... */ };

It's a bit tedious to do but it's not ambiguous. I did a similar thing
in the past when working on short closures. I tried using `{$x => $x
*2}` for the syntax and had to disambiguate with an empty block (which
serves no purpose in PHP). I can't find the branch/patch anymore,
which is unfortunate, but it is doable if you are determined.
