  # Since there are custom stages, the build matrix defined above for the 
  # test stage doesn't apply here anymore. Using YAML aliases to define 
  # test jobs here for all Lua versions without config duplication.
  # See: https://docs.travis-ci.com/user/build-stages/using-yaml-aliases/
  # 
  # Also... can't use `env:` here to specify Lua version, before_install
  # must be repated. This is because Travis cache is not shared between 
  # jobs with different env set.
