IMHO from inside deeply nested routines you can only to create a report, which is a $SIG{__DIE__/__WARN__} in disguise.

Anything else is maintenance hell.

Exceptions - which are not necessarily errors - should be handled as close as possible/reasonable otherwise you get "global" programming where you need to handle non local events.
