  Of course! And I strongly agree that static analysis is a good thing. But PHP still is a dynamically typed language and most of its development and usage is done with this dynamic approach in mind. It's not a XOR either, we can have better dynamic error reporting AND develop better static analysis tools at the same time. Also, due to the nature and usage of PHP, some things cannot be statically analyzed because they're inherently dynamic. A simple example would be MVC frameworks where the routing is done like so: /controller/action/param1/param2/param3 where "controller" references a class and "action" references a method, which will take the "paramN" as arguments through the splicing of an array: `$ctrl->$actn(...$args);`. In such situations it would be nice to have errors/exceptions raised automatically if the URL is wrong (not enough OR too much arguments) without having to manually assess everything inside each method. Since PHP 7 and 8 over we're moving away from long lines of isset() and !empty() (and verifications such as is_numeric() etc. thanks to argument typing).
