I think it's great, but in development. In fact it's so great that I edited my copy of CGI::Carp to send warnings to the browser too, instead of putting them in comments. But I always delete it when the script goes live. If the script breaks down when somebody else is using it then what I want is an errordocument redirect at the web server level to send them to a comments form to let me know what happened. I can then look at the error log to get the info I need to fix it. But the error messages are of no interest to anyone except (a) me or (b) someone I don't want to see them.
