You are not using strict and -w while testing to catch your little errors and speed development. But you then think it is fine to ask the entire Monastery to track down your mistakes?

What is wrong with this picture?

Telling people to use warnings and strict is like handing someone a fishing pole. It will catch a lot of your mistakes, and will prevent a lot of silly little questions that simple bugs tend to leave people with. I don't mind telling 15 people per day who don't know they need that wheel that they need it. I strongly mind dealing with one a week who knows it is there, and should know that it would prevent them from having a question to ask, but just couldn't be bothered to use it. That one makes me wonder whether I am wasting my time on the 15...

Please, if only for my sanity, stare at what chromatic told you, use strict, and try again. You already have a good answer. Use it and become a little more self-sufficient...
