That's one of the reasons why I prefer a magic methods based approach.

function __plus(...){}

can be searched for...and for future scope, something like:

function __union(...){}

is more self-documenting (imo) than:

operator  =E2=88=AA(...){}

Java is probably a better comparison language than C.

I have a note on the core problem that method overloading would face
for PHP here: https://phpopendocs.com/rfc_codex/method_overloading

But although they both involved the word 'overloading', operator
overloading, and method overloading are really separate features.

btw you can just say 'types'.

Unlike some lesser languages, in PHP parameter types are enforced at
run-time; they aren't hints. I believe all references to hints (in
relation to types at least) have been removed from the PHP manual.
