AFAICT, there is no way to automatically turn all warnings into fatal errors. But there is a way to do it per script, by replacing use warnings; by use warnings FATAL => 'all'; See attached patch to try it out.BTW in case we do find that there's some unforeseen problem and we want to roll back, it would be great to have a way to disable this without having to edit every single Perl file again later. However, I didn't find a way to do it -- I thought about creating a separate PgWarnings.pm file that would do the "use warnings FATAL => 'all'" dance and which every other Perl file would use or include; but couldn't make it work. Maybe some Perl expert knows a good answer to this. Maybe the BEGIN block of each file can `eval` a new PgWarnings.pm that emits the "use warnings" line?
Once we try it, I doubt we would want to revoke it globally, and if we did I'd rather not be left with a wart like this. As I mentioned upthread, it is possible to override the setting locally. The manual page for the warnings pragma contains details.
