Used as a to-do list specifically for what you want to remember to do, and adapted to your particular needs, Perl::Critic is pretty useful.
Sorry. But that "you can configure it to your needs" argument simply doesn't hold water. Let's start with the extremes:
... If I disable everything; what good is PC doing for me? It isn't But when I use the types of things it warns ne about; I do so with consideration at the time; what point is there to having it remind me?
For example: I purposely choose to use bareword file handles in top level scripts. I do this on the basis that different things should look different; and a top level script *OWNS* the global namespace so there is no conflict as modules should *never* mess with globals. And in modules -- complying with that rule -- I always use lexical file handles.
So now I would need two configurations for PC. And then another for another (personal) rule; and another; and another...SO then the game is deciding which of those configurations I should run against this particular script or module. But that is pointless because I already made my decision when I wrote the code.
And that's the second argument against PC. It does static analysis, after-the-fact. I do my analysis dynamically, as I write the code. Anything it chooses to tell me about, I've already made my decision about. (Or I don't want to hear it in the first place!)
And finally, it is completely possible to write totally unintelligible, crap, wrong and dangerous code that no amount of PC's static analysis will ever detect. Which means it still comes down to testing to determine whether the code does what it is meant to do or not. And once I've done my testing and concluded it works; I couldn't give two monkey's hoots whether some anal retentive, failed Perler, wannabe Java coder thinks the way I've achieved that is sliced bread or moldy goat's cheese.
Passing my tests won't guarantee that it is 100% bug free; but if it fails in use, it won't be down to anything that PC would have told me about.
