Hi Tim,

You're absolutely right. 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?

Best regards,
Sepehr
