Mikael always reminds that having short_loops enabled weakens the parser
ability to detect errors, so maybe it's worth mentioning here.

It's an occasion to me to tell the observation that function namespaces
would be rather more needed than variable ones. The point is that hook
plugins like z-sy-h and zsh-autosuggestions copy each widget to hook into
it. So it's ${#widgets}**2 functions out there with those plugins loaded,
and times of "lets see my functions print -rl -- ${(k)functions}" are over.
