Parser error triggers internal error

[muglug]

Not sure whether this is really a bug, saw on phpstan.org:

<?php return [,"a"];

Fixed, thank you! Surprised me parser lets this through :) phpstan/phpstan-src@a97477b

It's because the same object is used for array destructuring. Should change in v5: nikic/PHP-Parser#471

I know about that, but it could still have been a parse error when not on LHS of assignment :)
