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.
