I'd find the find($iterable, $callable, $default = null): mixed to be more user-friendly, personally, and would worry about accidentally increasing memory usage if I left one of those iterables around as a saved value or a long-lived local variable. There's plenty of time until the php 8.1 feature freeze, so I don't feel like increasing the scope of this RFC (https://wiki.php.net/rfc/any_all_on_iterable) even though I would find some version of find() with a callback useful.
