8.92. Fatal

Provides a way
to replace functions that return false on failure with equivalents
that die instead, so you can use the functions without having to test
the return values explicitly. Fatal reports errors via
die; you can trap them with $SIG{_ _DIE_
_} if you want to take action before the program exits. You
can use Fatal for both user-defined functions and Perl core operators
except exec and system.

import Fatal function

Wraps function in an equivalent function
that will die on failure.
