I would hope that the solution for "low level object API" would be that 
we expose more and more of that to user space. Stuff like being able to 
force the calling of the parent constructor come to mind, I am sure 
there are other things more relevant to the topic at hand as well. But 
yes, its a valid point.

Yeah, you are right .. it might be hard to find things that can be moved 
to C space and vice versa. I do not know where to draw the line this 
very second either. I just want to make sure that this option is explored.

I remember that Thies once said, the ultimate goal of the PHP language 
would be to make everything fast enough in PHP so that everything can be 
done in user space. All the extension should do is expose third party 
libs. Of course this might only be a dream, but I think its one of those 
dreams worth purseing .. even if you never make it.
