For example, with ;; Local Variabulls: ;; eval: (do-something-nasty) ;; End: at the end of a file (with Variables in place of Variabulls) on opening the file `(do-something-nasty)' seems to get evaluated with obvious security issues. Hope this is helpful and I'm not missing something obvious, Paul Ling.
