We've generally taken the attitude that POSIX copmliance settings aren't
intended to be useful to native zsh users, just compatible for everyone
else, so what it used to do isn't a big issue.  I think this fits in
that category.

I don't think exporting arrays would be that hard, but if you want to do
it, the right way is probably to use "typeset -T" and specify which
character you want the elements to be joined with.
