How many modules do you use?

use strict;
use warnings;

use v5.24;
use warnings;
use feature qw( signatures );
no warnings 'experimental::signatures';

use v5.24;
use warnings;
use feature qw( signatures );
no warnings 'experimental::signatures';
use autodie;
use List::Util qw( reduce pairgrep );

use v5.24;
use warnings;
use feature qw( signatures );
no warnings 'experimental::signatures';
use autodie;
use List::Util qw( reduce pairgrep );
use Try::Tiny;
use Log::Any;

Classes

use Moose;
use Types::Standard qw( :all );
use My::Types qw( :all );

use Moose;
use Types::Standard qw( :all );
use My::Types qw( :all );
use feature qw( :5.24 signatures );
no warnings 'experimental::signatures';
use autodie;
use List::Util qw( reduce pairgrep );
use Try::Tiny;
use Log::Any;

Roles

use Moose::Role;
use Types::Standard qw( :all );
use My::Types qw( :all );
use feature qw( :5.24 signatures );
no warnings 'experimental::signatures';
use autodie;
use List::Util qw( reduce pairgrep );
use Try::Tiny;
use Log::Any;

It's a Mess!

Now switch to Moo...

ack -g --perl pm lib | xargs sed -i.bak s/Moose/Moo/g # and pray

find lib -name '*.bak' -delete

Import::Base

All your modules in one place!

Create default imports

package My::Base;
use parent 'Import::Base';
our @IMPORT_MODULES = (
    'strict', 'warnings',
    feature => [ ':5.24', 'signatures' ],
    '-warnings' => [ 'experimental::signatures' ],
    'List::Util' => [qw( reduce pairgrep )],
);

use My::Base;

Imports strict, warnings, feature :5.24, sub signatures, and List::Util

Create import bundles

package My::Base;
use parent 'Import::Base';
our %IMPORT_BUNDLES = (
    Class => [
        'Moo',
        'Types::Standard' => [ ':all' ],
        'My::Types' => [ ':all' ],
    ],
    Role => [
        'Moo::Role',
        'Types::Standard' => [ ':all' ],
        'My::Types' => [ ':all' ],
    ],
);

package My::Class;
use My::Base 'Class';

Imports strict, warnings, feature :5.24, sub signatures, and List::Util.

Also imports Moo, Types::Standard, and My::Types

package My::Role;
use My::Base 'Role';

Imports strict, warnings, feature :5.24, sub signatures, and List::Util.

Also imports Moo::Role, Types::Standard, and My::Types

Good For Testing!

our %IMPORT_BUNDLES = (
    Test => [
        'Test::More', 'Test::Deep',
        'Test::Fatal', 'Test::Differences',
        'Test::Warnings', 'My::Test',
    ],
);

use My::Base 'Test';

Imports strict, warnings, feature :5.24, sub signatures, List::Util and all those test modules

Turn This

use strict;
use warnings;
use feature qw( :5.24 signatures );
no warnings 'experimental::signatures';
use List::Util qw( reduce pairgrep );
use Moo;
use Types::Standard qw( :all );
use My::Types qw( :all );
use Try::Tiny;
use Log::Any;

Into This

use My::Base 'Class';
