I think that the `is` operator is all we need; the `as` operator adds syntax complexity for little gain. Compare: $optionalExpiryDateTime = $expiry as ?DateTimeInterface else some_other_function($expiry); vs $optionalExpiryDateTime = $expiry is ?DateTimeInterface ? $expiry : some_other_function($expiry); —Claude
