New RFC just dropped: https://wiki.php.net/rfc/default_expression. I think some of you might enjoy this one. Hit me with any feedback.
Great work overall, I'm all for it and even though it's not something I saw myself using a whole lot, the json_encode example sold me on it being more useful than I initially thought. One question (sorry if someone already asked, I scanned the thread but it is getting long..): Taking this example from the RFC:
    function g($p = null) {
        f($p ?? default);
    }
Could you go one step further and use default by default but still allow null to be passed in?
    function g($p = default) {
        f($p);
    }
I suppose this would mean $p has to hold this "default" value until a function call is reached, at which point it would resolve to whatever the default is. This probably complicates things for very little gain but I had to ask. Best, Jordi
