This can't work.
Consider
<?php
class C {
public function __toString() { return "string"; }
public function __toArray() { return []; }
}
$result = str_replace(new C, new C, new C);
?>
Which method will be called?

Patches are certainly welcome, but be sure to get to every place, else
it becomes an inconsistent mess :)
Oh, and be consistent about return values of operations ... oh, and will
$result = some_array_operation(new ArrayObject);
return an array or instance of ArrayObject, if the later how will it be
instantiated ... do we have to pass result factories or something to all
of those?
