I only could find two from 2005.
http://news.php.net/php.internals/17491
http://news.php.net/php.internals/14558

It doesn't look like much discussion. I'm new to that web interface; not

Why don't we discuss adding this to the PHP6 release? I see it as a very
helpful addition and can't see a reason why we could not add it.

I'm developing a PHP framework and had the same issue sometimes... I
think
it was already discussed in the list, did you searched the archives?
