This has been tried with json via json-path, but there's no formal grammar or compliance test suite to back it. It's basically a really old blog post that has never been formalized. There's a much more robust alternative called jmespath that works across multiple languages and has a PHP implementation: https://github.com/mtdowling/jmespath.php I think this shows that this is a problem that can and has already been solved in user land (multiple times in multiple ways), and it can be done in a performant way (e.g., compiling expressions into PHP code). I don't see a need to add bloat to PHP's core for this. -Michael
