Bug report

When using PHP 8 named parameters, a false Dead Catch warning appears e.g.

try {
    $parsed = json_decode($contents, true, flags: JSON_BIGINT_AS_STRING | JSON_OBJECT_AS_ARRAY | JSON_THROW_ON_ERROR);
} catch (JsonException $exception) {
    throw new InvalidArgumentException('Unable to decode contents');
}

results in the error: Dead catch - JsonException is never thrown in the try block.
