O.K. the first for some reason may be wrong, but still the output is
baffling.

${(%)-%l} is ${-} is $- is the option flags. I can see why this might be
baffling, but I don't know what else zsh ought to do.

Hmm ... output an error message? I mean, ${(...)-} is an $-; but
${-blablabla} does not lool like it.
Or interpret it as the ${...:-...}?

But ${-blablabla} does print an error message:
zsh: bad substitution
The problem with ${(%)-%l} is the leading % sign in the stuff after the
parameter name. Would you expect ${(%)foo%l} to print an error message?
} Or interpret it as the ${...:-...}?
No, that would be wrong too.
