Hi Marco Pivetta,=0A=

I find that to be inconsistent with how other internal functions accepting =
callbacks such as `array_filter` behave.=0A=
It would also be unexpected if users or tooling wrap callbacks with other c=
allbacks.=0A=
Developers would also expect `func_get_args()` to work.=0A=
=0A=
```=0A=
<?php=0A=
function my_none(iterable $values, callable $predicate) {=0A=
    return all($values, fn(...$args) =3D> $predicate(...$args));=0A=
}=0A=
// PHP can't distinguish between these when given `fn(...$args)`=0A=
// - would throw if passed 1 parameter=0A=
my_none($values, fn($value, $key) =3D> $value =3D=3D true || $key =3D=3D 'x=
');=0A=
// - would throw if passed 2 parameters (too many)=0A=
my_none($values, 'is_string');=0A=
```=0A=

Thanks,=0A=
