Ruby 3.1 introduces a more performant anonymous block forwarding syntax that we should adopt once we freeze support for Ruby 3.0

Reading the issue, it sounds like this is not more performant - just syntactically simpler (no need to provide a block name). The original motivation was mostly about performance, but lazy proc allocation for blocks invalidated the performance rationale.

Not saying “no, don’t do this” - just pointing out there’s no performance benefit to doing so.
