title: How to load zsh/mapfile in ZSH
body: <p>I have installed zsh version 5.6.2 via brew. I am having trouble loading mapfile module.</p>
  
  <p>adding <code>zmodload zsh/mapfile mapfile</code> gives error <code>~/.zshrc:15: failed to load module 'mapfile': dlopen(/usr/local/Cellar/zsh/5.6.2_1/lib/mapfile.bundle, 9): image not found</code></p>
  
  <p>Anyone know how to debug this or a fix ?</p>
