and they develop modules/pragmas that bundle the above incantation plus
some additional stuffs. For example:
 
 use Modern::Perl '2018';
 
is equivalent to:
 
 use strict;
 use warnings;
 use feature ':5.26';
 mro::set_mro( scalar caller(), 'c3' );
 
I think Modern::Perl is one of the first to popularize this modern
preamble concept and a bunch of similar preambles emerged. This list
catalogs them.
 
Meanwhile, you can also use:
 
 use v5.12; # enables strict and warnings, as well as all 5.12 features (see L<feature> for more details on new features of each perl release)
 
and so on, but this also means you set a minimum Perl version.
