How about first implementing use() for anonymous classes first?
Something like:

function foo(int $outer) {
     return new class() use($outer) {
         public function getIt() {
             return $outer;
         }
     };
}

This would help with the main problem you expressed and be a less concern
for the future.

It's a different direction from what you suggested but it might be a lot
harder to pass a $^ syntax or similar.
