I don't know what is complicated about "string|Stringable" or "Foo|Bar" since it is super self-explanatory. However, I find myself checking the docs (IDE or online) in which order I need to pass arguments to one of the various mixed up functions in the core all the time. PHP is not easy, it has so many quirks that one needs to know of that you could make a PhD only for that. https://eev.ee/blog/2012/04/09/php-a-fractal-of-bad-design/ This contains A LOT of that stuff. -- Richard "Fleshgrinder" Fussenegger
