In this case, riba's referring to 'use warnings FATAL => ...;', or these days the specific subet of warnings that 'use strictures 2;' fatalises. Which is very much a trade-offs situation - I want e.g. an unexpected undef to cause my code to die(), because 'unexpected' means 'this might be a bug', and I'd prefer a crash to completing in an unexpected state and risking data corruption. I'm also happy to have code that dies on newer perl versions that didn't previously until patched, because the last time a newly added warning caused that to happen to a piece of my code, that also exposed a bug. I'm very conscious of the potential additional inconvenience to users as a result of this approach, but prefer inconvenience of the form of an unexpected crash over the increased risk of the code completing successfully from the POV of the surrounding application while having actually done the wrong thing. -- Matt S Trout - Shadowcat Systems - Perl consulting with a commit bit and a clue http://shadowcat.co.uk/blog/matt-s-trout/ http://twitter.com/shadowcat_mst/ Email me now on mst (at) shadowcat.co.uk and let's chat about how our CPAN commercial support, training and consultancy packages could help your team. _______________________________________________ List: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/dbix-class IRC: irc.perl.org#dbix-class SVN: http://dev.catalyst.perl.org/repos/bast/DBIx-Class/ Searchable Archive: http://email@example.com
