       Thanks to mxey, jawnsy and ribasushi for help with the design.

perl v5.36.0                                       2022-10-15                                     vendorlib(3pm)

       In a system distribution such as Debian, it may be advisable for Perl programs to ignore the user's CPAN-
       installed modules and only use the distribution-provided modules to avoid possible breakage with newer
       and unpackaged versions of modules.

       To that end, this pragma will replace your @INC with only the core and vendor @INC paths, ignoring
       site_perl and $ENV{PERL5LIB} entirely.

       It is recommended that you put "use vendorlib;" as the first statement in your program, before even "use
       strict;" and "use warnings;".

           #!/usr/bin/perl

           use vendorlib;
           use strict;
           use warnings;
           use SomeModule; # will only search in core and vendor paths
           ...
