<?php

            throw new InvalidArgumentException(
                'TableOfContentsWrapper nodes should have 2 children, found ' . \count($children)
            );
        }

        $inner = $children[1];
        if (! $inner instanceof TableOfContents) {
            throw new InvalidArgumentException(
                'TableOfContentsWrapper second node should be a TableOfContents, found ' . \get_class($inner)
            );
        }
