src/Collectible.php:50

• createFrom() accepts and preserves string-keyed iterables, but this PHPDoc now documents only integer keys. Widen the iterable key type to int|string to match the implementation and the toArray() return contract.

     * @param iterable<int, mixed> $elements The elements to populate the collection with.

src/Collectible.php:84

• createLazyFrom() has the same key-preservation behavior as eager collections, including string keys, but the PHPDoc now documents only integer-keyed iterables. Widen this to iterable<int|string, mixed> to keep the public contract accurate.

     * @param iterable<int, mixed> $elements The elements to populate the collection with.
