} But it's true you would then have to skip over shell options to find

} zparseopts spec that matches the zsh invocation-time option set?

Hmm, you really don't need to parse from the left, now that I think on it.

IFS=$'\0' cmdline=( $(</proc/$$/cmdline) )
(( scriptword = $#cmdline - ARGC - 1 ))
if [[ scriptword -gt 1 &&
      opt$cmdline[scriptword-1] != opt-c &&
      -r $cmdline[scriptword] ]]
then print This shell seems to be running script $cmdline[scriptword]
else print This shell does not seem to be running a script
