In zsh, you can use set -o cshnullglob to enable the csh behaviour, though you'd rather do ls -d (foo|bar)/* there. See also Why is nullglob not default?

@cas you need to test with {foo,bar}/*, the /* makes the difference. It's a nullglob issue.

I think you are misinterpreting what you are seeing because that seems very unlikely - the exit code is coming from ls, and ls doesn't care whether it's being executed by bash or tcsh (also, i tested it on my system, and got an exit code of 2 in both bash and tcsh). In any case, you probably don't want to be relying on ls to check whether a directory exists or not. Use test -d dir (or[ -d dir ] - [). If you need to test existence of more than one, you can use boolean && or || operators to combine tests, or use a for loop.
