Subject: [PATCH] wildcard variable test for `unused_result` validation

We talked about migrating these tests to using language version overrides but I lost the plot over the weekend :).

Can you suggest how I'd modify this? How would I opt into this feature with a language version override if there is not version in which we have it enabled?
