Subject: -u option does not work with recursive expansion?
Date: Fri, 15 Feb 2019 00:07:43 +0100
Message-ID: <20190214230743.drgd47wuwapj5os3@gmx.de> (raw)

Why does the recursive expansion of foo not trigger an error
message with the -u option?  Is that a bug?  Is there some
woraround to get the expected error behaviour in all cases?

-- snip --
set -u
unset bar
# ==> bar: parameter not set
echo $bar
# ==> no error?
echo ${${foo}}
-- snip --

 $ zsh --version
 zsh 5.3.1 (x86_64-...-...-gnu)
