Gosh, I had completely forgotten about ZEND_TRY_BINARY_OBJECT_OPERATION.
So I withdraw my statement about the only reasonable way to implement
operator overloading in PHP[1], and state that there is no reasonable
way to implement operator overloading in PHP at all (excluding
comparison and equality operations), since apparently, we cannot even
get the *only two* internal bundled classes to properly handle this.
Cf. <https://3v4l.org/gksqI/rfc#vgit.master> and
