No, I meant that `\` is the character that separates namespaces *in PHP code*, so that typing `\` should trigger completion of namespaces members.

```php
<?php

namespace Ns {
	class Cls {
		static function f() { return 42; }
	}
}

namespace { /* root namespace -- yes, that's how PHP actually does it, too */
	echo Ns\Cls::f(); /* see how fun it is! */
	/* BTW, a leading \ makes the namespace resolution absolute, rather than relative to the current one */
	echo \Ns\Cls::f(); /* same as above */
}
```
