<?php

$children of type League\CommonMark\Node\Node[]|array is incompatible with the type Traversable expected by parameter $iterator of iterator_to_array().

                'TableOfContentsWrapper nodes should have 2 children, found ' . \count($children)

        if (! $inner instanceof TableOfContents) {
