Re: use utf8 pragma with moo

Within your Moo based module, try this:

package Foo;

use Moo;
use Data::Dumper;

warn Dumper [sort keys %INC];



1;
[download]

On my system with Perl 5.32 I get the following output:

$VAR1 = [
          'Carp.pm',
          'Config.pm',
          'Data/Dumper.pm',
          'Exporter.pm',
          'Foo.pm',
          'List/Util.pm',
          'Moo.pm',
          'Moo/Object.pm',
          'Moo/_Utils.pm',
          'Moo/sification.pm',
          'Scalar/Util.pm',
          'Sub/Util.pm',
          'XSLoader.pm',
          'bytes.pm',
          'constant.pm',
          'mro.pm',
          'overloading.pm',
          'strict.pm',
          'warnings.pm',
          'warnings/register.pm'
        ];

So you can see that the utf8 pragma isn't enabled by default by Moo.

Can you provide a self-contained code snippet that demonstrates the namespace::clean issue? Also within the namespace::clean documentation, it does mention that you can pass an -except => [qw(foo bar)]; list of subs not to clean. Doing so may improve your experience.

Thank you very much for "warn Dumper sort keys %INC" - this is brilliant. The problem with namespace: `use utf8; use feature qw(signatures); no warnings qw(experimental::signatures); use Moo; use namespace::clean; sub BUILD($self) { $self->_set_count(1); }` [download] An error: "The signatures feature is experimental ..." Should I place no warnings after namespace::clean or there are other solutions? Maybe with namespace::clean -except?	[reply] [d/l]

The "problem" with Moo is that it re-enables all warnings that you previously disabled. So a solution is to disable warnings after the `use Moo;` line: `use utf8; use feature qw(signatures); use Moo; no warnings qw(experimental::signatures);` [download]	[reply] [d/l] [select]

The "problem" with Moo is that it re-enables all warnings that you previously disabled That's odd ... why has the right to "Do What I Don't Mean" been bestowed upon Moo, when that sort of thing is generally frowned upon ? Thankfully, I don't use Moo and have no interest in it. However, I have just installed it to verify that it actually has this most unperlish capability ... and it does !! What's the spin that validates this ? Cheers, Rob	[reply]
