version 0.25
package CheckingService; use Bubblegum::Role; sub deposit { my $self = shift; my $amount = $self->balance + shift // 0; return $self->balance($amount); } sub withdrawal { my $self = shift; my $amount = $self->balance - shift // 0; return $self->balance($amount); } package BankAccount; use Bubblegum::Class; with 'CheckingService'; has balance => ( is => 'rw', default => 0 );
And elsewhere:
my $account = BankAccount->new(balance => 100000); say $account->withdrawal(1500);
Bubblegum::Role provides an object orientated system for defining class components (often referred to as traits or roles) by way of Moo::Role; and activates all of the options enabled by the Bubblegum module. Using this module allows you to define Moo roles as if you were using Moo::Role directly.
use Bubblegum::Role;
is equivalent to
use 5.10.0; use strict; use autobox; use autodie ':all'; use feature ':5.10'; use warnings FATAL => 'all'; use English -no_match_vars; use utf8::all; use mro 'c3'; use Moo::Role;
