Good reminder, thanks! Implementation would indeed require support
from PHP, say:

// magic-method __decorate implies that __construct would return
$this->__decorate(func_get_args(), $f); and enforce @ as
annotation-syntax
class Dec1 {
    function __decorate($args, $f) {
        return $f;
    }
}
class Dec2 { ... }

@dec2
@dec1
function foo() {}

means this:

$foo =3D new Dec2(new Dec1(new ReflectionFunction('foo')));
Perhaps ... $foo =3D @Dec2(@Dec1(new ReflectionFunction('foo')));
