I.E. can you replace global use and require statements with a lazy loader such as autouse or Class::Autouse.

Alternatively, can you require modules just in time?

    # conditional use of require
    if ($heavy_lifting_needed) {
      require BigModule;
      ## BigModule->import(); # maybe
      BigModule->do_stuff();
    }

• if your code is organised into discrete modules
• only some of them are being used in any particular hit
• you're not importing symbols into your namespace
