I'd point out that if you state a reasonably modern version of Perl
you don't need to turn on strict, it's turned on for you.  If you use
Moose (or several other modules out there) then warnings get turned on
for you too.

At $work in our key codebase we find demanding all these strictures
tiresome.  We instead have a standard line that you need to put this
into your source:

 use OurSecretProjectName::Strict;

(If you don't the test suite will fail and our build system will get
angry with you.)  This module turns on a bunch of handy strictures:

package OurSecretProjectName::Strict;

use strict;
use warnings;
no indirect 0.24 ":fatal";
no multidimensional 0.008;
use Sub::StrictDecl 0.003;

sub import {
        strict->import;
        warnings->import;
        indirect->unimport(":fatal");
        multidimensional->unimport;
        Sub::StrictDecl->import;
}

sub unimport {
        strict->unimport;
        warnings->unimport;
        indirect->import;
        multidimensional->import;
        Sub::StrictDecl->unimport;
}
