Hmm ... I think that has something to do with this:

% arr[2]=two
% arr[2][1]=Z
zsh: no matches found: arr[2][1]=Z

That is, there's a level deeper than where namerefs operate that
doesn't parse past the first subscript.  I'm not sure how hard to work
on that (or if we even want the latter case to work).

I'll keep a note of it, though.
