That's not quite accurate, though.

% print -l ${|reply| reply=(a b c)}
a
b
c

It's only ${| REPLY=...} and ${ command } that always behave like scalars.

Even ${| REPLY=(a b c)} behaves like a scalar (joins the array), which
I suppose is also worth mentioning.  Will consider wording over the
weekend when I have more time.
