Thanks for your feedback, Larry! > One possible improvement to either version is allowing an expression on the left side. That > is, rather than doing an equality match, do a boolean match. This is how Rust does it: ```rust let x = match ... { Some(y) if y < 5 => ... } ``` In other words, you can add an additional guard to each case that excepts any expression. We don't really benefit a lot from that since we don't have pattern matching. I don't think this would add any significant benefit over: ```php $x = true switch { $x !== null && $x < 5 => ... } ``` Regards
