title: Perl module naming convention
body: <p>I have checked
  <a href="http://pause.perl.org/pause/query?ACTION=pause_namingmodules" rel="nofollow noreferrer"><em>On the Naming of Modules</em></a>,
  <a href="https://perldoc.perl.org/perlvar.html" rel="nofollow noreferrer"><code>perldoc perlvar</code></a> and
  <a href="https://perldoc.perl.org/perlmod.html" rel="nofollow noreferrer"><code>perldoc perlmod</code></a>
  but can not find best practices for naming modules whose name is an acronym: <code>SMTP</code>, <code>ORM</code>.</p>
  
  <p>At once on CPAN both variants names are seen: <code>SMTP</code> and <code>Smtp</code></p>
  
  <p>If my new module name is an acronymthen<br>
  what would be the better name for it: <code>My::Module::Abcd</code> or <code>My::Module::ABCD</code>?</p>
