bor@itsrm2% print ${(%)-%l}
5679KNTXYZhims
bor@itsrm2% print ${(%):-%l}
pts/9

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

} bor@itsrm2% print ${(%)-%l}
} 5679KNTXYZhims

${(%)-%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.
