I think the division between E_NOTICE and E_WARNING is a bit arbitrary 
sometimes, but without a good definition of the difference, I think it's 
unhelpful to introduce "inflation" by raising severities. Don't forget 
that while an undefined variable is sometimes an error, it's sometimes 
just poor coding style, and the user is consciously relying on the 
implicit null (e.g. $count++, or $hash[$key] = $value, or even echo 
$hash[$key]).

Perhaps what's needed is a survey of current messages, and an RFC to 
reclassify them based on some consistent definitions?
