Hey guys, I still haven't finished reading the looong thread on aggregation vs. MI because you guys write so much :) I would like to make a proposal for a solution which I think would fit PHP very nicely. My main concern with MI is that there are many problems with it including namespace

BTW: Have you looked at my patch to handle method calls differently? Yes and I don't like it. I haven't had time to do timings yet. I was very busy and will try and do it in the next few days. hmm The patch wasn't just for speed it was more for sloving 2 main problems. class a

If you want to access an aggregated object directly you can do: $obj-Timer-method(); well, that's exactly what shouldn't be done and what polymorphism is trying to eliminate... consider a huge code library which operates on an object of class Timer and that we want to reuse this library. now

PHP isn't a compiled language and we aren't going to start adding casting, v-tables and so on. PHP is extremely loosely typed and doing $obj-foo calls the method foo on $obj. This also allows for things like: $blah = foo; $obj-$blah; and so on. I really think that people who are looking for

i'll try to answer both Marcus and Wez here: Where is the big difference (first is postfix syntax, second is prefix syntax). the difference is between whether you have to change *lots* of existing code or do exactly *one* cast in new code while you write it: $timer = (Timer) $MI_obj;
