Whilst trying to work out how to denote the type of an expanding object-like-array I ran into this issue (see Psalm bot below).

Having posted it as a discussion it was suggested that Psalm should likely handle this situation, so here we are!

I found these snippets:

```php 1]; $data = array_merge($default, $data); return $data; } ``` ``` Psalm output (using commit a96645d): ERROR: InvalidDocblock - 8:1 - Intersection types must be all objects or all object-like arrays, Psalm\Type\Atomic\TKeyedArray provided in docblock for appendUser INFO: MixedArgumentTypeCoercion - 10:33 - Argument 2 of array_merge expects array, parent type T:fn-appenduser as mixed provided ```

I think the error correct in the example provided since T is mixed, however, the error still stand:
