fair enough. Thanks.

In ksh, there is no way I know of making var refer to an array because it
expands to the first element of the array and with [@], you get a bad
substitution.

Comparing with bash, I have to use [@] to get an array before the
modifier. With the [@], both bash and zsh work the same regardless of
quotes. So basically, I haven't been able to create a comparable situation
in bash or ksh.

I still think the behaviour seems odd mainly because I'm used to reading
these substitutions from the inside out and the double quotes are on the
outside.
