(This entry is motivated by the announce of the new version of this module)
I've been using it for a while and thinking about if I should continue with that or come back to my old "print $var if error" (ilustrative example). Then, a program crashed. And The message was there, in its logfile. Beautiful.
I don't need to say that I've updated the module
This is a great module.
