The new syntax in PHP 8.6 makes using array_filter incredibly clean and elegant, and I completely agree on the readability aspect. However, my main motivation for this RFC is performance. When dealing with large arrays, the overhead of executing a callback (even a built-in one) for every single element in array_filter can be quite significant. A dedicated function implemented purely in C would bypass that overhead and execute much faster. Do you think the performance gain for such a common use-case justifies having a dedicated function, or do you feel the language should strictly prefer the array_filter approach despite the overhead?
