Leaving $opts[@] unquoted still elides empty elements in this
context; that behavior is not limited to $@.  (If this is what you
actually want, go for it.  Just don't think that fiddling with
options has an effect.)

It's better to run ''emulate -L zsh'' inside the function itself
(or localize and [un]set options individually as desired) to achieve
a known state, rather than relying on a specific method of invocation.
