When you call die from inside a module, you should probably be using croak instead (and carp instead of warn). These two methods are available from Try this little exercise, save the following as
package Foo; use Carp qw(croak); use base qw(Exporter); our @EXPORT_OK = qw(gonna_croak gonna_die); sub gonna_die { die "ya got me!" } sub gonna_croak { croak "ya got me!" } 1;
Now use that module with the following one-liners:

$ perl -MFoo=gonna_die -le gonna_die
ya got me! at line 7.

$ perl -MFoo=gonna_croak -le gonna_croak
ya got me! at -e line 1
die reports the error from the actual line it was executed on, which might be many packages deep. croak, on the other hand, reports the error from the perpestive of the caller, which is usually more useful to the end user. The end user usually cares more about which line of their code caused the problem, not which line in the module it affected.
