No flames, so long as you know you're wrong ;-) just kidding. Seriously though it's dependent on the end user. If they are the curious type and will actually attempt to understand the modules they use then that's good. I just rewrote a script from years ago that I used to select 5 random lines from a file that was atrocious, no scoping, vast assumptions (one of which was causing it to get locked in an infinite loop! Very Bad since it was run by cron), etc. etc. So I got Algorithm::Numerical::Shuffle and the script is now much more stable and trivial. And I really think that it would have been best for me to have used it in the first place long long ago. I would have been more confident in the script (or justifiably so), and spent time on making it work well instead of just making it work. On the other hand I wouldn't have been able to (it would have unnecessary) revisit it and see how very far I'd come ;-).
