After about a month of being with perl monks I have noticed that most of you religously push use strict and -w. While I have learned to use strict, and appriciate it's contraints, I found -w a little more annoying.

First let me mention that I mainly write CGI programs. Most of the programs that I write run multiple times, each time acting as a different program. This is basically because I like to keep everything in one file, it eliminates the need for a central config file, and I like the portability. However this also means, that only certain variables are used in certain parts of the overall program, and that -w fills up my error_log with 'Use of uninitialized value'. I do not see any problem with having variables that only ocassionaly do something, besides taking up file space.

Basically, I'm asking, Is this something I should worry about? Here are some possible solutions, the last being my favorite.

• Break up my programs into separate files.
• Attempt to recode my programs to eliminate these warnings.
• Put up with the warnings.
• Just don't use -w when coding like this.

I would appriciate any insight you might have on the matter. For an example of the coding technique I am reffering to, check out my DB Mangager.
