G'day kp2a,

You may find one or more of these to be useful (some you may already know about):

• The 'refs' stricture of the strict pragma. (The other strictures generate compile-time errors.)
• Promote warnings to fatal errors.
• Use eval to trap errors.
• Use Carp routines to produce more verbose warning and error messages, including stack traces.
• Use caller to get varying amounts of information from just the caller's package to a complete stack trace.
• Write $SIG{__WARN__} and $SIG{__DIE__} handlers (see %SIG in perlvar).
• Take a look at the information provided by the $!, $?, $@ and $^E Error Variables.
• Use autodie to trap errors from specific functions.
• CPAN modules such as TryCatch and Try::Tiny. Take a look at their SEE ALSO sections for similar modules.
• A CPAN search for 'exception' may prove fruitful.
