To be honest, I'm not facing a bunch of situations where I particularly want to avoid strict, warnings, etc. Or, rather, I want them to be worked out before production because if they happen in production and they're masked, I may never know that my data got silently munged.

As for the logging, warn-fatal, etc., I probably want most of those either in a logfile or in my commandlines (or both).

I standardised our logging tools and exception handling mechanisms by centralising them in a Log module. Admittedly, it isn't a great mechanism, but it does suffice for our purpose. And it's the same code for all our scripts. I also standardised a lot of other things by putting them in modules. Such as commandline handling.

I'm not saying your idea isn't good. I'm saying that if it is, I'm currently missing it.
