    function f1() {}
}

abstract class abstractClass {
    function f1() { }
    abstract function f2();
}

class D extends abstractClass {
    function f2() { }
}

class privateConstructor {
    private function __construct() { }
}

$classes = array(
    "C",
    "iface",
    "ifaceImpl",
    "abstractClass",
    "D",
    "privateConstructor",
);

foreach($classes  as $class ) {
    $reflectionClass = new ReflectionClass($class);
    echo "Is $class instantiable?  ";
    var_dump($reflectionClass->isInstantiable());
