Test::Most, not Test::More. That's a very important difference here.

But that doesn't change my arguments. I wouldn't want any module to turn on a pragma in the calling scope - unless that is its specific purpose. turn::on::all::pragmata should turn it on. But not something from the Test::* namespace.

I'd say that reducing boilerplate code is one of the main advantages of Test::Most, so I think it will be logically if it will enable strict and warnings. The people who don't love surprises and magic can always replace it with:

use strict;
use warnings;
use Test::More;
use Test::Exception;
use Test::Differences;
use Test::Deep;
use Test::Warn;

It's not that I think the person typing in use Test::Most will be surprised.

It's the person inheriting the code.
