While solving http://bugs.php.net/bug.php?id=27974,
we've discovered that `count()` on an overloaded object
(in this case, a variant object representing an OLE
SafeArray) doesn't return a truthful value.

What, if anything, are we going to do about that?

We could add a hook to the C iterator API for `count()`;
it shouldn't have a huge impact on the rest of the engine.

I talked about this with Marcus a few months ago.  I think that objects 
which implement the necessary interfaces should work as arrays in all 
the standard array functions.  Marcus had an old patch for this that I 
would be happy to help update if people are keen on this idea.

I'm not sure if the Iterators API is the right place (it's an API for 
foreach()). I guess it could be in either the Iterators API or the Object 
API. What would you expect it to return as far as PPP properties is concerned?

By the way, I was holding off RC2 because of that bug you found. Any news? 
Can I roll RC2?
