Something I also noticed back in May, and which I'm now reminded of, is
that test/[ returns status 1, and not 2 or higher, if an error occurs.

$ [ x = a b ]
[: too many arguments
$ echo $?
1
$ [ 1 -eq ]
zsh: parse error: condition expected: 1
$ echo $?
1

This makes it impossible to test for the failure of test/[ using the
exit status.

POSIX says the status should be 2 or higher on error:

Thanks,
