} Hmm ... output an error message? I mean, ${(...)-} is an $-; but
} ${-blablabla} does not lool like it.
But ${-blablabla} does print an error message:
zsh: bad substitution
The problem with ${(%)-%l} is the leading % sign in the stuff after the

} Or interpret it as the ${...:-...}?
No, that would be wrong too.
