NAME

       Modern::Perl - enable all of the features of Modern Perl with one import

VERSION

       version 1.20240115

SYNOPSIS

       Modern Perl programs use several modules to enable additional features of Perl and of the
       CPAN.  Instead of copying and pasting all of these "use" lines, instead write only one:

           use Modern::Perl;

       This enables the strict and warnings pragmas, as well as all of the features available in
       Perl 5.10. It also enables C3 method resolution order as documented in "perldoc mro" and
       loads IO::File and IO::Handle so that you may call methods on filehandles. In the future,
       it may include additional core modules and pragmas (but is unlikely to include non-core
       features).

       Because so much of this module's behavior uses lexically scoped pragmas, you may disable
       these pragmas within an inner scope with:

           no Modern::Perl;

       See <http://www.modernperlbooks.com/mt/2009/01/toward-a-modernperl.html> for more
       information, <http://www.modernperlbooks.com/> for further discussion of Modern Perl and
       its implications, and <http://onyxneon.com/books/modern_perl/index.html> for a freely-
       downloadable Modern Perl tutorial.

   CLI Usage
       As of Modern::Perl 2019, you may also enable this pragma from the command line:

           $ perl -Modern::Perl -e 'say "Take that, awk!"'

       You may also enable year-specific features:

           $ perl -Modern::Perl=2020 -e 'say "Looking forward to Perl 5.30!"'

   Wrapping Modern::Perl
       If you want to wrap Modern::Perl in your own import() method, you can do so to add
       additional pragmas or features, such as the use of Try::Tiny. Please note that, if you do
       so, you will not automatically enable C3 method resolution in the calling scope. This is
       due to how the mro pragma works. In your custom import() method, you will need to write
       code such as:

           mro::set_mro( scalar caller(), 'c3' );

   Forward Compatibility
       For forward compatibility, I recommend you specify a string containing a year value as the
       single optional import tag. For example:

           use Modern::Perl '2009';
           use Modern::Perl '2010';

       ... both enable 5.10 features, while:

           use Modern::Perl '2011';

       ... enables 5.12 features:

           use Modern::Perl '2012';

       ... enables 5.14 features:

           use Modern::Perl '2013';

       ... enables 5.16 features, and:

           use Modern::Perl '2014';

       ... enables 5.18 features, and:

           use Modern::Perl '2015';

       ... enables 5.20 features, and:

           use Modern::Perl '2016';

       ... enables 5.24 features, and:

           use Modern::Perl '2017';

       ... enables 5.24 features, and:

           use Modern::Perl '2018';

       ... enables 5.26 features.

           use Modern::Perl '2019';

       ... enables 5.28 features.

           use Modern::Perl '2020';

       ... enables 5.30 features.

           use Modern::Perl '2021';

       ... enables 5.32 features.

           use Modern::Perl '2022';

       ... enables 5.34 features.

           use Modern::Perl '2023';

       ... enables 5.36 features.

           use Modern::Perl '2024';

       ... enables 5.38 features.

       Obviously you cannot use newer features on earlier versions. Perl will throw the
       appropriate exception if you try.

       As of Perl 5.38, you may prefer to write "use v5.38", which is almost entirely equivalent
       to the use of this module. For the purpose of forward compatibility, this module will
       continue to work as expected--and will continue regular maintenance.
