title: What is corect way to configure path to packages for perl?
body: <p>I may configure location of packages for perl via <code>PERL5LIB</code>, <code>-Ipath/to/libs</code> option, <code>use lib LIST</code>. But what if I add paths into <code>@INC</code> manually: <code>BEGIN{ unshift @INC, './local' }</code></p>
  <p>Why perl do not add add <code>site_perl/5.30.3/x86_64-linux</code> and <code>5.30.3/x86_64-linux</code> automatically?</p>
