"This is going to cause us MONTHS (to fix)". Whether he is right or wrong, you cannot say he's not over-exaggerating and being a pain in the ass. Also, expecting "" to == 0, when it's easier and proper to enter 0 just doesnt make sense. That's like saying "i expected your software to make up for me not using it correctly". Sass or not from the guy who wrote PHP, this guy is just a pain in the ass and his complaint is ridiculous.

ADDITION: As the creator stated, it's been issuing warnings for some time now and was changed LAST YEAR. there's just no foundation to this complaint.
