I found these snippets:

https://psalm.dev/r/09ffdd3f6a

<?php

/** @param string[] $ids */
function(array $ids): array {
    return \preg_replace_callback('', fn (array $matches) => $matches[4], $ids);
};

Psalm output (using commit fc8212e):

INFO: PossiblyUndefinedIntArrayOffset - 5:62 - Possibly undefined array offset 'int(4)' is risky given expected type 'array-key'. Consider using isset beforehand.

INFO: MissingClosureReturnType - 5:39 - Closure does not have a return type, expecting mixed
