libmodern-perl-perl binary package in Ubuntu Focal amd64

 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 since Perl 5.10.
 .
 For enabling features of newer Perl releases, a year can be specified as an
 import tag, e.g.:
 .
    use Modern::Perl '2017';
 .
 enables 5.24 features. Cf. Modern::Perl(3pm) for details.
 .

 Modern Perl and its implications, and
