vendorlib - Use Only Core and Vendor Libraries in @INC



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


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;.


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