Instead of arrays I much prefer using specialized data structures from ext-ds extension:

• https://github.com/php-ds/ext-ds
• https://www.php.net/manual/en/book.ds.php
• https://pecl.php.net/package/ds

Unfortunately Tracy dumper seems unable to show me the contents of the data structures which often leads to important info to be missing on the exception screen.

If I understand Tracy correctly then this should be possible using \Tracy\Dumper::$objectExporters.
