Hey,

Am I right in assuming that aggregation is going to be removed in PHP5?

How could I live without aggregation or multiple inheritance? 

I have a choice, I prefer the latter. But not a 100% MI as I know there 
are a lot of debates on 100% MI. What I would like to see is a 
aggregation like MI. Say 

class foobar extends foo, bar {}

The methods and properties foo has will have higher priority than bar when 
being inherited by foobar. So parent::method will be foo::method. As of 
properties, a class can always initialize its properties in a method or 
even constructor when it is to be extended at a second place.

Bar's constructor will not be called automatically. 

It actually _is_ aggregation right? But without deaggregation and so that 
no exteral hash table outside Zend, hence no bug like in PHP4.

That's my little simple proposal of aggregation-like multiple inheritance. 
Agree?

  Java developers are very happy without these concepts. Why? Because
  they have interfaces. Guess what? We have them, too.

Yep, interfaces replace them...
