Oddly enough, though I'm fairly dogmatic about warning against the evils of coding without strictures, I forget to use strict now more than I used to. This is because I test so thoroughly that I catch bugs early. Then when I'm sitting there scratching my head over a code failure, I check and see that I forgot to use strict.

So if you're testing thoroughly, strict isn't as much of the big deal some make it out to be. However, if I come along later and add strictures to your code and it fails, I'd be mighty unhappy.
