Stas, thanks for this.  Seems that w/ __invoke() in 5.3 if a method property
is_callable then the engine should check for that and call it.  I realize
the problem now though, in php instance variables can have the same
identifier as instance methods therefore collisions could exist, for example

class B
{
  function __invoke() {}
}

class A
{
  public $c = null;

  function c() {}
}

$a = new A();
$a->c = new B();
$a->c();

seems i got the notion this would work from javascript, however i also
realize the reason it works there, only a single identifier is allowed which
would map to either a scalar or a function object and in the later case
would be invokable.

the implementation in php make sense to me now.

thanks for your time,
