I just learned about the proposed cache PSR, and I have to speak up.

I must apologize in advance, as my tone may get harsh or sarcastic, but it really upsets me to see a proposed standard which probably a lot of developers will end up following, to their detriment.

First off, FIG is the "Framework Interop Group" - did you actually look at other frameworks to see what they're doing? ZF2, Laravel, Doctrine, Symfony and Yii, to name a few of the major ones - not a single one of those use an aggregate model for individual cache items. How exactly is this standard supposed to help these frameworks interoperate?

For another, none of the cache providers you're going to be wrapping with this interface use an aggregate model - and for the most part this is probably deliberate, because the operations on a cache are supposed to be very focused and atomic, allowing you to optimize by doing as little work as possible.

This kind of thinking seems

	<?php

	// a performance baseline for the PHP version / platform / etc.:

	foreach ($values as $i => $value) {
	$sum += $value;
	}

	$avg = $sum / count($values);

	$error = array();
