Bubblegum::Object::Undef - Common Methods for Operating on Undefined Values
use Bubblegum; my $nothing = undef; say $nothing->defined ? 'Yes' : 'No'; # No
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.
my $nothing = undef; $nothing->defined ? 'Yes' : 'No'; # No
The defined method always returns false.
