NAME

Object::NulStr - Object which stringifies to NUL character ("\0")

VERSION

version 0.02

SYNOPSIS

use Object::NulStr;

die Object::NulStr->new; # dies without seemingly printing anything

DESCRIPTION

Object::NulStr is like Object::BlankStr, but instead of stringifying to "" (empty string), it stringifies to "\0" (NUL character). This has the benefit of having a boolean true value so checking exception is simpler (a simple if on $@ will do). But Object::BlankStr might suit you better if printing "\0" has some undesired side effects. Too bad we can't have it both ways for now.

So far the only case I've found this to be useful is for die()-ing without printing anything. If you just use 'die;' or 'die "";' Perl will print the default "Died at ..." message. But if you say 'die Object::NulStr->new;' Perl will die without seemingly printing anything.
