EXP30:EX1: There are several instances when die() and warn() are preferred over carp() and croak():
- Inside a signal handler . This is because the behavior of
croak()andcarp()functions when invoked inside a signal handler are not documented.
- Outside a subroutine, that is, when used in a small Perl script. In this case, all four functions have no stack trace to indicate their calling location.
