Setting "hyper" to mods only crashes Hammerspoon

[ihodes]

E.g. from the README:

(local config
       {:title "Main Menu"
        :items menu-items
        :keys  common-keys
        :enter (fn [] (windows.hide-display-numbers))
        :exit  (fn [] (windows.hide-display-numbers))
        :apps  apps
        :hyper {:mods [:shift :alt :cmd :ctrl]}})

Results in this error:

.oon.app/Contents/Resources/extensions/hs/hotkey/init.lua:416 that is a limitation of Hammerspoon currently. When #72 gets completed that could provide a reasonable entrypoint to allow users to replace the underlying machinery. In this case we're using the hs.hotkey functionality which is more opinionated. With an advising system in place you would be able to redefine the one function responsible for listening for hotkeys and use the raw hs.eventtap functionality instead.

I just noticed the same. The config in the main readme (hyper section) itself causes this crash, so it should probably be removed.

This suggestion was removed from the readme, since we can't support it due to hammerspoon itself.
