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.

ACK, that bites, I was so looking forward to multiple inheritance. I
hate interfaces *heh*.

Cheers,

Yep, interfaces replace them...
