Sorry, I'm a bit confused. The previous link is to the zsh source code mirror on GitHub, specifically the definition for _store_cache which is what calls zstyle and mkdir. 

Do you mean that, in this particular case, radian should include these two zstyle commands above in its setup? But if zsh provides a fallback, is this really a requirement?

FYI - I left out that I traced brew, which calls _store_cache at  https://github.com/Homebrew/brew/blob/16b2a14c9408140b04828462b660d30056421fdb/Library/Homebrew/completions/zsh.erb#L143
