Exceptions thrown during yield operation fall through the generator instead of being handled within

Description

The following code:

<?php

set_error_handler(function() { throw new \Error(); });

function &gen() {
    try {
        yield 1;
    } catch (Error $e) {
        print "Caught";
    }
}

foreach (gen() as $y);

Resulted in Uncaught Error

But I expected this output instead:

Caught

return_by_ref has the same problem, it seems to me, however in generators there's the additional case of exceptions in destructors of previous key and values.

I wouldn't change the longstanding behaviour in current PHP versions, but should be fixed for PHP 8.2 possibly, for academical correctness at least.

Reproducir el ejemplo de generator proporcionado en PHP master y comparar el flujo de errores observado con el comportamiento esperado de catch. Después, inspeccionar el manejo de yield en generators, el comportamiento de retorno por referencia y los casos de destructor indicados. Se considera terminado cuando el manejo de excepciones previsto esté definido y cubierto para los escenarios reportados, sin cambiar involuntariamente el comportamiento establecido.
