This can already happen with other magic methods. For instance:
class A {
public function __set(int $foo, int $bar) {}
}
$a = new A;
$a->test = 42;
# TypeError: Argument 1 passed to A::__set() must be of the type int,
string given
As long as the implementation correctly unwinds the stack when a Throwable
is encountered (__toString *can't* cope with this, and bails out the
engine), I don't think this is a problem.
