perl-strictures

I've been writing the equivalent of this module at the top of my code for about a year now. I figured it was time to make it shorter. Things like the importer in 'use Moose' don't help me because they turn warnings on but don't make them fatal -- which from my point of view is useless because I want an exception to tell me my code isn't warnings-clean. Any time I see a warning from my code, that indicates a mistake. Any time my code encounters a mistake, I want a crash -- not spew to STDERR and then unknown (and probably undesired) subsequent behaviour. I also want to ensure that obvious coding mistakes, like indirect object syntax (and not so obvious mistakes that cause things to accidentally compile as such) get caught, but not at the cost of an XS dependency and not at the cost of blowing things up on another machine. Therefore, strictures turns on additional checking, but only when it thinks it's running in a test file in a VCS checkout -- although if this causes undesired behaviour this can be overridden by setting the 'PERL_STRICTURES_EXTRA' environment variable. If additional useful author side checks come to mind, I'll add them to the 'PERL_STRICTURES_EXTRA' code path only -- this will result in a minor version increase (e.g. 1.000000 to 1.001000 (1.1.0) or similar). Any fixes only to the mechanism of this code will result in a sub-version increase (e.g. 1.000000 to 1.000001 (1.0.1)).
