I have no real experience using exceptions in my code. Neither I have not seen good guide how to use exceptions in software developent. I have lot of small pieces about it, but no big picture. So I have simple question: how and where to catch errors in Dancer app? 

I looked to Dancer::Error and it seems good, but still I don't get, where is the best place to catch and handle errors? Is it good idea to have one simple dispatcher (like in bin/app.pl), so every exception is falling to the base script and handled there? Or is better to catch them in place all over the code? Or? Is there some "best practice"?
