NAME
Object::SpaceBackStr - Object which stringifies to space+backspace ("
\b")
VERSION
version 0.02
SYNOPSIS
use Object::SpaceBackStr;
die Object::SpaceBackStr->new; # dies without seemingly printing anything
DESCRIPTION
Object::SpaceBackStr objects are like Object::BlankStr and
Object::NulStr objects, but stringify to space+backspace (" \b") so when
printed they don't seem to output anything.
Choosing between the three: Object::BlankStr truly doesn't print
anything as it stringifies to an empty string, but since empty strings
are false in Perl it has some gotchas (see Object::BlankStr
documentation for more details). Object::NulStr stringifies to "\0"
which are also invisible in most terminals when printed, but when it
doesn't work, you can try if Object::SpaceBackStr does.
So far the only case I've found this to be useful is for die()-ing
without seemingly printing anything. If you just use 'die;' or 'die "";'
Perl will print the default "Died at ..." message. But if you say 'die
Object::SpaceBackStr->new;' Perl will die without seemingly printing
anything.
