VERSION

version 0.35

SYNOPSIS

use Bubblegum;

my $nothing = undef;
say $nothing->defined ? 'Yes' : 'No'; # No

DESCRIPTION

Undefined methods work on variables whose data meets the criteria for being undefined. It is not necessary to use this module as it is loaded automatically by the Bubblegum class.

METHODS

defined

my $nothing = undef;
$nothing->defined ? 'Yes' : 'No'; # No

The defined method always returns false.
