Bug description:Enabling factory constructors
Description:
------------
It would be nice to be able to create factory constructors (like Dart
offers).
This could be achieved by allowing __construct to return an arbitrary
object of
the same class or a descendant thereof.
No return statement would then mean "return $this;" as it is today.
Sure, one can use a static factory method, but it's not as elegant and
cannot
simply be added to existing code without modifying all places where objects
are
instantiated.
Test script:
---------------
class MyClass
{
public function __construct($id)
{
if (isset(self::$cache[$id]))
return self::$cache[$id];
// Do expensive setup
self::$cache[$id] = $this;
}
private static $cache = array();
}
