missing space before `use` + too long line, split in 2

```php
$filename = $reflector->getFileName();
$parsed = static::getCache()->derive('parsed')->load($filename, function(&$dp) use ($filename, $class) {
```

or rather 3

```php
$filename = $reflector->getFileName();
$cache = static::getCache()->derive('parsed');
$parsed = $cache->load($filename, function(&$dp) use ($filename, $class) {
```
