So this takes a single $op, such as "-z", and a single $arg, which is supposed to be a literal value? Feed them into the test external to test them outside the shell:

Code:
if test "$op" "$arg"
then
...
fi

test won't support the full extended zsh syntax, just the basic bourne. It won't evaluate any shell code or variables whatsoever and will never make your program quit from syntax error. If someone tries inserting multiple things into $op to be tricky, it just won't work.
