(see https://docs.github.com/en/developers/overview/using-ssh-agent-forwarding)

Tiltfile

  The following macro will introduce an alias into the calling module replacing
  the last part of the module name with the contents of List.replace_at/3.

  This is useful if you want to automatically references a different module 
  without knowing the fully qualified module name, but I'm new to Elixir and
  there may be a better way to do this.
