It'd be no more problematic than any other facility that supports including
sub-files, for example texinfo. And, if you think about it, the same
could be said for #'require or #'load in elisp where doing something
malicious would only need the right #'provide form and getting to the
head of the load-path.
In my pseudo-example above, if it were real world, obviously FILENAME is
replaced with a path to a, hopefully, existent file.
Wait, here's another idea from the crazy-dept. Use a hash, like a md5
or sha1 or some such of the file to be included. Before the inclusion,
check the hash, error out if there's a mismatch.
Local variables:
@include-hash: f31785c629584f30116ff45aa681fa5318613fd9
@include: FILENAME
End:
> Better to refer to something above in the file.
I'm not a huge fan of file-local variables or special "cookies" or
whatnot at the best of times, so I'm not going to say what would be
"better". :-)
