Contract
- Uuid::fromString returns a LazyUuidFromString instance that implements UuidInterface but does NOT inherit from Uuid
- UuidInterface::getHex returns a Ramsey\Uuid\Type\Hexadecimal value object where is_string is false and strict comparison with a string returns false
- UuidInterface::getInteger returns a Ramsey\Uuid\Type\Integer value object rather than a string or integer primitive
- UuidInterface::getDateTime returns a DateTimeImmutable instance that implements DateTimeInterface but does not inherit from mutable DateTime
- Uuid::isValid rejects 32-character unhyphenated hexadecimal UUID strings even though Uuid::fromString successfully parses them
