Oh, yes and special methods that you mentioned would come in handy too

method to clean un-referenced objects would also be handy.
How does that differ from $x=null; with a reference-counting garbage
collector?
Cheers,

When Im talking about something like this would come in handy
obviously doesnt work! The paramter null could be added, to get
desired result but to be programmatically correct:
class MyOverload{
function __construct($Foo) {
$this->Foo = $Foo;
}
// overload the constructor
function __construct(String $Foo, String $Bar){
$this->Foo = $Foo;
$this->Bar = $Bar;
}
public function doSomething(){
if($this->Foo != null && $this->Bar == null){
return $this->Foo . " needs a partner";
// do something with Foo
}elseif($this->Foo != null && $this->Bar != null){
return $this->Foo . " and " . $this->Bar . " are partners";
//do
something with Foo and Bar
}
}
private $Foo;
private $Bar;
}
$obj = new MyOverload("Mary");
print $obj->doSomething();

It would be nice to have a base class to inherit some special
methods as we do in Java.
could you name which ones you think of?
being out of the JAVA camp for several years know i no longer
know all java.object methods and properties by heart, but
PHP mechanisms like __sleep()/__wakeup(), __toString() and
the introspection related functions like get_class() and
friends should provide comparable behaviour ...
(IMHO the fact that any object in JAVA can be casted down
to java.object is not that clever after all, and part of it
is only due to the fact that there is no other way to have
portable container classes, which is now finally solved
with generics)
The same as method overloading,
one of the most important aspects missing in PHP5 and the
new object model.
due to the feature of optional parameters you may end up with
more than one overloaded function matching a call signature,
due to the fact that argument types in a function call
are not known at compile time signature matching would have
to happen at runtime,
and the language syntax would need to be extended to add
parameter type specifiers to function parameter declarations
(ok, we already have this one for interfaces ...)
