Re: When should you not use strict and warnings?

in reply to When should you not use strict and warnings?

I never switch off use strict but I used to disable use warnings for production code (but only after it ran clean of course).

Nowadays I always use Modern::Perl with enables both strict and warnings and I do not bother with disabling it anymore in production code. In rare cases I might locally disable irrelevant but well understood warnings for unititalized variables.

I use Perl mainly for transforming data from one format to another and when an unexpected "unitialized variable" warning crops up, it ususally means that there is something wrong with the data and the parser I wrote has failed to match some data to a variable, hence the warning. I think this warning is a nice last resort catch-all line of defence and I would not want to miss it.


A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James

Corion watches from the sidelines. Or rather, from behind, as my system only gets output from that process and my programs adhere strictly to the GIGO design principle.
[erix]: ah, that's nice to hear Corion :)
[Corion]: erix: Yeah, the sad thing is that all I can do is document things, so I can point fingers when the auditors come :-/
[Corion]: "I'm here to open tickets and point fingers. And I'm all out of tickets."
[erix]: didn't Sybase have pretty good auditing? :) (this is a vague memory)
