I just spent three frustrating, heartbreaking, suicidal hours catching this bug. I was getting to the point that I started doubting my understanding of the most basic perl. 
      my @run = MyClass->find_all();
      if(@rum){
           # do something,
      }else{
           #do something else
      }

The problem was that the "if" test always fail where it shouldn't. And I caught the bug after I put "print Dumper(@run)" after the first line, in other words, I was willing to accept that may be "if(@rum)" isn't what I think it is after all!

Of course, the bug was that I wrote "if(@rum)" instead of "if(@run)" (and my emacs font/coloring made it barely distinguishable). Why didn't I use strict? because I always use strict, I tell everyone to use strict, I've used strict all my life, and somehow I didn't this time, and I thought I was using strict!

I read some recent post here to the effect that "you don't have to use strict if you know what you're doing", I couldn't disagree more. I'd say, use strict, check twice you're using strict, and ask someone else to check you're using strict. You will live longer if you do.
