Those PITA warning messages are little hints that the craftmanship of the code is below par. Perhaps one in a thousand warnings can be ignored. The other 999 need to be addressed. An example.
Yesterday and today I had to write quick scripts to get some stuff done on a Production system. Normally I'd do a one-liner or cobble something absolutely horrible together, cross my fingers and go with it.
Instead, I wrote POD, used Getopt::Long to handle arguments, used or die $usefulMessage in all of the appropriate places. Yes, it took a little longer to write, and I tested as I went .. but the result was that these little utilities worked absolutely fine. Then what?
Then I checked them into our version control system so that I would know where to find them the next time I needed them. So now I have documented, commented, error checking utilities that I can pull out of my hat (so to speak) the next time we need to do X.
It all comes down to a matter of craftmanship. If my scripts and modules compile 100% clean, if I never have errors in my error logs, that's a sweet way to be.
So fix your code -- banish all warnings!
