} Is there some option (for example --check-syntax) such that

$ zsh -n /path/to/some/file
or equivalently but more obviously
$ zsh -o no_exec /path/to/some/file
will parse but not execute the file, and exit with failure if there is
a parse error. However, just because a file doesn't cause a parse error
is not a guarantee that it is a shell script, and parsing a very big
file is potentially expensive.
