Object translator No.2

[milo]

Another approach of #429

API is:

Connection::setObjectTranslator(string $class, callable $translator): void

# e.g.
$connection->setObjectTranslator(Email::class, fn($email) => new Expression('?', $email->address));

If you consider it useful, last commit changes API and the target class is detected from $translator parameter typehint:

Connection::setObjectTranslator(callable $translator): void

# e.g.
$connection->setObjectTranslator(fn(Email $email) => new Expression('?', $email->address));
