### Description

The following code:

```php
<?php

function foo(string $key): string {
    throw new \Exception('Test');
}

array_filter(
    array_combine(
        ['a'],
        array_map(j::foo(...),['a']),
ay_combine(
        ['a'],
        array_map(j::foo(  ['a'],
        array_map(j::foo(...),['a']),
ay_combine(
        ['a'],
        array_map(j::foo(...),['a']),
    ),
    ...),['a']),
    ),
    ),
);

?>
```

Resulted in this output:
```
