Re: Bug report: `setopt noaliases` not respected in `local` statement without assignment.

Aha. So, if I want that aliases don't get expanded in the functions in
https://github.com/junegunn/fzf/blob/master/shell/completion.zsh, then
where should I put the `setopt noaliases` statement? Does it suffice to
just put `emulate -L zsh; setopt localoptions noaliases;` at the top of the
file? I don't want the noaliases option to leak into my own shell
environment.

Or is there a better solution possible here than using noaliases?
