From a tooling point of view, it would be super-interesting to get a FQN of
the function, instead of a closure (which is just `\Closure`).

In this snippet, I'd expect the output to be `foo\bar\baz\taz`:

```php
<?php

use function foo\bar\baz;

echo baz\taz::function;
```

Not sure if `string` is enough, but it worked really well for `::class`,
for which tools like psalm now have a dedicated `class-string` type :-)
