[PEPr] Comment on PEAR::PEAR_Exception

I think this RFC is a bit misguided. I have had this on my plans for a long time but never found the time - I would love if someone took on this initiative. The package xml for this is already ready: https://github.com/pear/pear-core/blob/master/package-Exception.xml - for the most part. It didn't help that PEAR had deps on PHP 4, so the only viable option was to make PEAR_Exception depend on PHP 4 as well. That way PEAR could depend on PEAR_Exception and not the other way around, thus on the new PEAR update people would get PEAR_Exception. If we move PEAR it self to have a min dep on PHP 5 (5.1.6 or 5.2 perhaps) then PEAR_Exception can dep on PHP 5 as well and everyone is happy. No confusion. Package authors can them self do releases (or QA) with a new dep on PEAR_Exception instead of PEAR, but it won't be required to do a mass updated on all packages. I want to see this done but not in the confusing manner proposed. -- http://pear.php.net/pepr/pepr-proposal-show.php?id=679
